Server :: Sendmail Not Forwarding Email To Domain's SMTP?
Apr 9, 2010
I have a server "test1" in domain [URL]. I installed sendmail on it. I have another mail server "mailsrv" installed in [URL] which is my primary mail server and contains all accounts and mailboxes. Now when I send email to [URL] from [URL] it sends successfully. But when I try to mail to user1@abc.com it tries to search user1 in [URL] but I want it to forward this mail to mailsrv.abc.com over SMTP port. Delivery will then be taken care by [URL]
My log shows following
Code:
Apr 9 18:37:06 test1 sendmail[7512]: o39Db6Hs007512: to=user1@abc.com, ctladdr=root (0/0), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30047, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (o39Db6Il007513 Message accepted for delivery) It should not go to relay=[127.0.0.1], it should go to relay=[10.10.10.1]
I am thinking about buying a domain name and hosting my web server.
I have seen pricing from $8 to $30 a year. Any favorites from fellow ubunters? Also this whole "whois" thing scares me, if I am correct my information I enter when buying the domain is enter into some big pool of information. People can find this information out and dig up important information. url Can I prevent this with private Whois or how do I set it up? This website examples some of my fears with this whole WhoIs thing, url whois/Private-Whois.html Does most/all domain registers come with email or just email forwarding or both? How does that work? At this moment, my only question about Web Hosting is how do I get Website Statistics as in: Stats, web analytics, web traffic stats and more? I will be web hosting through Ubuntu 9.10 gnome.
I have an issue with sendmail. I need to configure sendmail to send email from command prompt to any domain. This is just for the notification purpose. I installed sendmail and sendmail-cf and sm-client. The following are the configuration I have done.
dammit... all that typing and I hit the wrong "submit" button. *sigh*
Ok, I have a couple of SMTP servers for our infrastructure. They are running Postfix. I have them configured so that specific email addresses such as support@mydomain.com and billing@mydomain.com all go to a new support server that I am building with osTicket. Lets call that server SUPP1.
SUPP1 runs sendmail from the default install of CentOS 5 i386. At this point everything runs great. New emails get added into the osTicket system via a pipe in sendmail. Here's where the problem comes in. In order to accept mail, sendmail has to have the domain listed in local-host-names and the addresses in virtusertable. That works just dandy. But in doing so, sendmail believes it is the destination SMTP server for "mydomain.com". That means that I can't send mail from that server back into my normal SMTP servers. So things like the LogWatch, cron jobs, etc can't send notifications. Is there a way to work around that? For sendmail to ignore local-host-names for outbound email or something?
I am a bit of a linux newbie, but have been gradually teaching myself how to set up Sendmail 8.13.8 on a CentOS system to handle our MX mail for various domains we own on our local server. Configuration has gone well so far, except I cannot seem to get Outlook to authenticate with the SMTP server and I must readily admit to some large gaps in my knowledge. For testing purposes, I have tried to authenticate using Telnet with the following results:
Code: 220 my.domain.com ESMTP Sendmail 8.13.8/8.13.8; Wed, 3 Aug 2011 14:27:00 GMT ehlo my.domain.com 250-my.domain.com Hello mytelnethost.btcentralplus.com [109.xxx.xxx.xx], pleased to meet you 250-ENHANCEDSTATUSCODES
How do I automatically forward mail to a different user on a different machine in my LAN? I have been beating my head for several hours trying to accomplish this. I have sendmail configured as an MTA solely to receive system mail from daemons. For my personal mail I just use KMail and POP. I want all mail on any system in my LAN to forward mail to my office system, where my normal account can receive the messages. Although my office machine is powered on the most often, the box is not available 24/7.
So any other system that can't immediately forward mail should keep that mail queued as long as necessary. I have no problem forwarding root's mail on each local machine to a local user account on that same machine. I have been able to forward the mails but not the way I want. The mails get forwarded to the local /var/mail/me location rather than into the remote office machine /var/mail/me. Adding another alias in the local /etc/mail/aliases has no effect.
Creating ~/.forward in the local user's home directory also has no effect. Both efforts always result in the mails being forwarded to the local location rather than remote. I can send user-to-user email to and from any machine on my LAN. There are no network problems between any machine. Basic forwarding does work, just not to a remote machine at a different account. I won't pretend to know much about mail systems, let alone sendmail.
is that my isp's smtp service is very poorso i want to configure my own smtp servr for my internal clients only for sending emails not receivingi have static ip on my router with 25 port forward i have configure sendmail on linux its working fine on local network mean its sending email on local domainnow i want to send emails on other external domains with my public ipMean user of mydomain.com should be able to send emails on all internet domains like yahoo.com, hotmail.com etc
It seems my sendmail (running in slackware 13.0) cannot send out emails correctly. I guess I need to tell it what is the smtp server to use. And, I heard, gmail's smtp server is available to use for this purpose. How to configure my sendmail this way?
I've got a server set up with Debian. The problem is that my ISP doesn't allow usage of port 25 (as I understand a lot of ISP's don't).I have PHP scripts hat use the mail() function to send e-mails through the Sendmail application.So, my question is: How can I relay messages sent to sendmail to an external SMTP server (like Google Mail, for example)? Would this be easier to do in the PHP configuration, or on the Sendmail side of things?I've used PEAR extensions in PHP to achieve this before, but scripts downloaded from the Internet generally just use the basic mail() function, and it would be a real pain to modify them all.
I'm hoping someone here can help, as I've been beating my head on the wall for a week now with little advancement. I've found a number of tutorials on setting this up, however none of them have gotten me 100% of the way there. Here's my situation: home-based Fedora server (Core 8), running sendmail 8.14.2-1. Connecting to hosting company's smtp server over port 587, to bypass Verizon's blocking of port 25.
My /etc/mail/sendmail.mc file looks like this (comment lines removed):Quote:
I got one last stop until I've fully configured my Sendmail server. I want the server to verify which address the sender is using when sending mail. Even though authenticated via SMTP AUTH or mailing from an IP listed as RELAY in access.db, the user should not be able to use whichever address he likes.
Ideally, I would like Sendmail to use a file that looks something like this: Username sername@Server.org
where, if logged in with Username, the only accepted sender address is Username@Server.org. As of now, Sendmail just verifies that the sender domain exists and then relays which I don't like. This also applies to a lot of other servers as well... for example in the cases where ISPs have blocked outgoing port 25 and let all their users use their SMTP server. I assume, if they don't use SMTP AUTH which is not the case where I am, that they have their entire IP range listed as RELAY and therefore, using my ISPs SMTP when in their net, I can send mail as whomever I like as long as the sender domain exists.
I've had a look at filters but haven't found any suitable and I assume that this might be realised through a Ruleset or something. What do you think? Have I missed something making this a really stupid suggestion or am I on to something? It would make my day
Sendmail on the RHEL server is set up to forward email to company internal mail server (via SMART_HOST). This has worked fine for years.
From the server, doing a sendmail dave@company.com, the message is sent immediately. No problems - and no change here.
From the server, doing a sendmail roberto@compania.com (compania is the part of the company in Mexico) causes a 2m40s delay before sendmail does anything.
No packets are sent until after 2m40s wait. Message is always sent after the delay. It is not clear what the server is waiting for.
For *each* user in the @compania domain specified in sendmail command, an additional 2:40 is imposed before email is sent. Email is always sent after the n*2:40 sec delay.
Sending email to some_name@AnUnusedDomainNameThatDoesntExist.com is processed immediately - with a bounce email received in a couple of seconds.
Q: How do I determine where this 2m 40s delay is introduced?
I want to run a DMZ postifx smtp relay that will collect and relay several domains, this I can do. But is it possible to then relay each domain to a different server?If so how ? and what set up is needed.
I am setting up a CentOS box as a NAT firewall that needs to also send mail. It needs to send this mail using an outside provider's SMTP. The provider requires SMTP over SSL. None of the machines inside the NAT will ever send mail except via the provider's SMTP nor will they ever receive mail except to local clients via the provider's IMAP servers.
So for the example the machine is TESTMACHINE. There is one internet facing ethernet port connected to a DSL modem via pppoe.
The SMTP it needs to send mail via is mail.host.net which requires SMTP over SSL (port 465) and username/password authentication.
The sendmail documentation is quite confusing on how to get this simple setup operating, so an example showing the appropriate changes to sendmail.mc and other require config files.
I've been having this problem since 10.6 released, but have until now been successful with the "just use Thunderbird" response. My sendmail server hasn't been changed, but as clients upgrade from OSX 10.5 to 10.6 suddenly mail.app will no longer connects to send SMTP messages through the server. (IMAP connections to the same server using the same user/pass combinations work perfectly) When I look at the logs, things basically stop right after the STARTTLS command.
Google indicates alot of people are having similar problems, but I'm not seeing any solutions. Do any of you administrate sendmail servers where some of your clients are using Apple's Mail.app on Snow Leopard, and if so what settings are you using? At this point, I'm happy to make changes to the server to accommodate Apple's issue, I have too many Mac users connecting to my server. I just can't figure out what to change. I've enabled virtually every possible login authentication combination, and none of them work.
I have set up 10.04 server, got userdir working (/home/username/public_html) so I can access it with h ttp://myipaddress/~username. What do I need to do to get mydomain.com to point to http://myipaddress/~username?
I am looking at setting up a multiple postfix SMTP servers for a single domain. Below is my requirement, I would appreciate if someone out there could guide me to achieve this using postfix..
1. Want to setup 2 postfix SMTP Server with 1 POP3 Server.
2. Server1 will host POP3 & SMTP services for domain "metallica.one".(IP: 1.1.1.1, MX: mx1.metallica.one)
3. Server2 will host only SMTP services for domain "metallica.one" (IP: 1.1.1.2, MX: mx2.metallica.one)
4. Server1 & Server2 will be used as load balancing for sending mails. (either manual settings in email client, or auto-loadbalancing is still preferred).
5. Mail received for domain metallica.one on Server2 should be pushed/forwarded/relayed to Server1 where POP3 services are running.
6. Outgoing mails for other domains from Server2 should be sent directly to the other-domain-recipients without relaying to Server1.
I have a server that runs on a static IP address with many hosting accounts. I am using the IspCP to manage the different sites. When a mail is sent, the headers include the box's own domain name: [URL]. Now [URL] is no longer active, so if an email from another account: [URL] sends mail, there is possibility that this mail is rejected by the receiver, if the receiver system does rDNS.
The receiving server will check the headers smtp sent from [URL] and come up as a fake, because [URL] is no longer registered. I wonder if there is a way to make the smtp headers reflect only the domain name that sent the mail. Then if joe sends mail, the server should replace[URL] with [URL]. If this is possible, then users that send mail will not get bounced because the rDNS lookup will map [URL] to the ip and the mail will be accepted.
I have a Centos 5.5 Server, Servername is CentOS1. It has a Forum and a HelpDesk. The Help Desk software SENDS and acknowledgement to the user and emails to all the people on the support desk. Users can reply to emails only by accessing the helpdesk NOT by mail. Thus the server is configured to only SEND mail and not to receive any mail at all.
Mail Server is Sendmail. Hosts file reads : - # Do not remove the following line, or various programs that require network functionality will fail. 127.0.0.1CentOS1.tech.xxxxx.com CentOS1 localhost.localdomain localhost ::1localhost6.localdomain6 localhost6
There is NO MX Record because this server receives NO mail, it's send only. Unfortunately, the mail it sends has a From Header which is @CentOS1.tech.xxxxx.com. I want it to send from @xxxxx.com. I've read all the howtos on Masquerading and I've tried many, many things, but with the same results. It will NOT change the From. I had it working perfectly a long time ago with a SuSE server, but I can't for the life of me remember what I did. I know I also battled a bit.
The last few lines of sendmail.mc read : - LOCAL_DOMAIN('localhost.localdomain')dnl dnl # dnl # The following example makes mail from this host and any additional dnl # specified domains appear to be sent from mydomain.com dnl # dnl MASQUERADE_AS('xxxxx.com')dnl dnl FEATURE(masquerade_envelope)dnl dnl FEATURE(masquerade_entire_domain)dnl dnl MASQUERADE_DOMAIN(localhost)dnl dnl MASQUERADE_DOMAIN(localhost.localdomain)dnl dnl MASQUERADE_DOMAIN(CentOS1.tech.xxxxx.com)dnl dnl MASQUERADE_DOMAIN(CentOS1)dnl dnl MASQUERADE_DOMAIN(tech.xxxxx.com)dnl MAILER(smtp)dnl MAILER(procmail)dnl dnl MAILER(cyrusv2)dnl
I've tried each one of the MAQUERADE_DOMAIN in turn, none of them work and yes, I have remade it.
Has thunderbird (recent version) have a "TEST" function ? basically, i'm trying to send messages, with 20+ accounts (different emails, but one domain / SMTP server). one account works fine - the other one doesn't. i go to my "outgoing server" & everything is fine - usernames / ports etc..) The settings for each account do show the right outgoing server. If i 'send later' & close down thunderbird, 7 re-open - it asks me for my password again (which it saves), & then it is able to send the email.
QUESTION :- is there a TESt option that will test each & EVERY account in one timeslot ? Ie, will go through each email address - sends an email to itself (the same address), & sends it. it will then try the server again, to see if the email was received. & then give me a single report, of all the incorrect settings.(I've tried this 1 email account half a dozen times tonight & i dont know *WHY* its not sending on the 1st go.. )
Id like to ask you some advice. Im currently using as mail server Lotus Domino. Because of many reasons I need to create an SMTP server that receive the email from Dominothat relay those email into an authenticated SMTP on the internet. How can I do that? I create a Debian virtual machine and I installed Postfix. I edit the config file and set the relay host (authenticated SMTP on internet),the mtp_sasl_auth_enabled and smtp_sasl_password_maps parameters. If I try to send an email using that SMTP server I got a message that say âśRelay access denied, check the email address†What did I do wrong
I want to block a domain name in sendmail server. I added the domain name and "REJECT"in /etc/mail/access file. What has to be done for the changes to take effect? when i run make command in /etc/mail dir i get following error : make: Nothing to be done for `all'.
I am using sendmail. I want to apply sendmail restriction so that nobody cannot send any mail to other domain.my domain name is msp.net E.g. 1. rahul.com 2.kumar.com I want to send mails only above two domain only.if any user want to send mail to other domain. It should be not reach. What should I change in sendmail.mc or in my firewall?
I have sendmail installed in my home machine and also dns is configured and also I have configured mx for mail server. My dns is unregistered and my question is that can I send mail to external account like yahoo or gmail to check whether my is working or not.
I'm Trying to setup Sendmail to work with my domain in my server which is :

I have a recent install of Fedora14, and wanted to have outbound email sent to a smtp server elsewhere on the local network. I found the System->Preferences->Email Settings app and created a mail account with an smtp server. Now I am able to use mailx, mutt, and sendmail -- all send email correctly to the external server.
But I don't like being reliant on the GUI apps and wanted to know how this was done -- what system config files were affected. Assuming that my "smtp.xxx.com" server should show up somewhere, I grepped /home, /etc, and /var, but can't find it anywhere. On a whim I went into Evolution, deleted the mail account, and rebooted, but email STILL works. Where is this configured?
Having my Diploma Final Project on setting up a virtual mail server within Local Area Network (LAN) only. I had follow this how-to [URL] and complete up to squirrealmail web mail. I added two new user to try on sending and receiving mail. It works. I run CentOS on VMplayer. I using my laptop to do all the stuff, the laptop default OS is windows 7, I install VM player on it and run CentOS inside the VM Player.
I want to do testing on Windows 7 side by installing Thunderbird email client program, I want to connect to mail server with SMTP, IMAP/POP3 using the email service. I have problem while setting up user account on Thunderbird, Thunderbird seems like cannot detect my CentOS mail server. How? Do I have to do any other configuration on CentOS? Any DNS? Port number for IMAP, POP3 or SMTP?
I have users [URL] unable to send email to [URL]. [URL] user also unable to send email to [URL]. But both email addresses are fine as they can receive email from others or from [URL] and [URL]. I able to telnet mail server 110 and 25, no problem. Version: ESMTP Sendmail 8.12.10
