Red Hat :: Sendmail 8.13 - Can't Send Mail To Own Domain
Jan 13, 2010
i have running sendmail 8.13 on my red hat enterprise linux 5.1, but i have a problem. I can send a mail from my line command terminal to hotmail, gmail, yahoo and any of these, but i can't send mail to my own domain ([URL]), when i wrote a mail i get a reply from MAILER-DAEMON@localhost.localdomain that says that the message had pemanent fatal errors and shows as user unknown the mail was suposed to recive the message.
For example, if i send one mail from firstname.lastname@example.org to email@example.com the user2 does not recive any mail, but that doens not happens if user1 sends a mail to any hotmail address or gmail or any other. Besides i also can't recive on my server any mail to firstname.lastname@example.org or email@example.com (for example), so please tell me what do i do to get the mail.
I had configured sendmail on linux 5.2, Iam using public ip and my domain is registered[linuxforfreshers.info]. I am facing a issue that when I mail with the user firstname.lastname@example.org then I am able to do it. But if somebody tries to send mail to the same user then it bounce backs. I had made the entry of domain in /etc/mail/local-host-name and also I put ok in /etc/mail/access.The mails are working properly with in LAN. But not able to work on WAN only I can send mail but not able to recieve mail.What else I need to do.

I'm currently running Ubuntu 10.10 Server using VirtualBox 3.2.12 r68302. I've setup a LAMP Server and Installed Redmine and I'm going to be starting some projects. The problem I have is that I've linked it to a subdomain thru my hosting, so things are a little more complex for me then usual. Here's the software I've added for this setup:
Ruby version 1.8.7 (i686-linux) RubyGems version 1.3.7 Rack version 1.1
how mail server functionality works as well as how to properly set the host of the virtual pc.
I have a CentOS 5.2 server with hostname support.companyname.local It's used to run Request Tracker 3.8.1. I need to be able to send email from this machine and make it look like the email came from firstname.lastname@example.org instead of email@example.com
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.
There is an requirement, intranet people they may not have internet access but they want to send mail to external domain(internet),but in that intranet network one machine can have internet access. Is there any solution for this requirement.
I have one major problem in my mail server. I am not able to send mail to other domain yahoo and rediff. and my ipaddress is blacklisted. So Finally I checked logs. Mail queue is high. Log shows spam and junk mail created in my mail server. he following are the logs. Iam using qmail server. One more thing is in link is there when I click that link its go sex websites. I will try all mail queue logs. It shows the same website redirection. So I don't know its happen. My thought is spam create from that website.
I've struggled with this problem for days. I cannnot send mail to an external address with sendmail. I can receive and send local mail and I can receive external mail. I am sending out of a router. At wits end, I am providing as much information as I can imagine will be helpful to help me solve this. The stated culprit is this host unknown error. But I know the mail server smtp is correct: url. I even checked the nyclug if anyone had problems with road runner. I can telnet localhost, the url mailserver. I know the port 25 is open. I suspect that I need to change host server name in etc/host, but I have had no success. Is this an access file issue? Is gmail just bouncing back my mail? I want to solve this because that is what we do. I understand that I could use another application, but lets solve this one.
I just configured my first postfix mail server today. Everything is working correctly except for the fact that on all outgoing emails instead of the mail format being firstname.lastname@example.org it says user@hostnameofpostfixserver. I've looked everywhere I can think and I cant see where I'm substituting the host-name of the server for the domain name of my email. Where else could it be?Below is my main.cf. I am running ubuntu 9.10.# See /usr/share/postfix/main.cf.dist for a commented, more complete version# Debian specific: Specifying a file name will cause the first# line of that file to be used as the name. The Debian default
I am managing a Fedora dedicated server with Plesk 9 and just recently moved the email for one of the domains on the server to Google Apps for business. Unfortunately, I cannot get email messages from the website forms to deliver to addresses on this domain. For anyone familiar with Plesk, I have disabled mail in the hosting settings by un-checking the "Activate mail service on domain" checkbox and there are no accounts in the domain. (Other readings have indicated that this should be enough to allow mail to be directed to the appropriate server). My MX records correctly point to the google apps mail server.
I'm quite comfortable with command line, but I know almost nothing about the sendmail program or its alternatives and my attempts at researching how to set up this relay has been futile. I'm pretty sure I'm using sendmail and not qmail or anything else from what the red-hat style "alternatives" symlinks point to. I've also checked the /etc/mail/access, domaintable, mailertable, sendmail.cf, virtusertable, local-host-names, sendmail.cf, and submit.cf and most of these files are empty (except the .cf files), and the sendmail.cf and submit.cf make no reference to the domain in question.
Here is the output from a sendmail test that was was not received. (Private data omitted of course). sendmail -v email@example.com test email from yyy.com webserver. please ignore. firstname.lastname@example.org... Connecting to [127.0.0.1] via relay... 220 my.server.com ESMTP >>> EHLO my.server.com 250-my.server.com ..... Closing connection to [127.0.0.1] >>> QUIT
Performing the same test and sending an email to a non-hosted domain works fine.
I have a server with a static IP that I use as a sendmail server. The problem is that port 25 is exposed. As a result, anybody can login to the SMTP server and send mail from my domain as a user that does not exist as well as email from other non-existant domains. I'm sure there are sendmail options that I can enable to do some checks, like if the user exists on that server or if the domain is the same on the server, etc. I was wondering if you guys can mention a few that I can add to my sendmail.mc file?
I have thought about auth login, the problem is if auth login is on my public port then I won't be able to receive email from gmail because it would be unauthenticated. Also, I only have 1 mail server. I know the ideal solution is to have 2 mail servers. One for outgoing mail/internal mail server where you can enable auth login and the other for incoming mail which just acts as the relay to the internal mail server. That way spammers can't login to send mail out. That's another question I had, how do I configure sendmail to only send email out/in?
Anyhow, so I have to make do with 1 mail server for now. So I decided to add a few rules on iptables. I grabbed the IP range that gmail uses when I receive mail from then and added it to my iptables with the following command.
I want to configure a single mail server to send and receive mail from multiple sub domains of my domain. I've already installed Postfix/Dovecot and it is perfectly working for mydomain.com. And also installed roundcube for Web Mail. Can I further customize this setup to process mail to sub domains? ex- email@example.com, firstname.lastname@example.org, email@example.com (firstname.lastname@example.org and email@example.com are 2 separate users. they should be able to log on to web interface separately)
Currently i use system account names as email user names. (ex - firstname.lastname@example.org). The only MX record in my domain DNS pointed to current server (mailhost.mydomain.com). I read about postfix virtual domains. but couldnt figure out how to use it to achive my target. I do not need configuration details. Just explain me the way to do it. I can do the rest my self.
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

I'm an Oracle DBA and started working for my current employer about 4 months ago. This past weekend an alert re: FS space brought my attention to /var/spool/clientmqueue (full of mail re: cron jobs) and the fact that sendmail is not running on our Linux servers.I'm told that the IT security team deemed sendmail too vulnerable so we don't run it.Aside from FS filling up and missing notification of issues with crontab entries, I'm concerned that we may be missing notification of potential issues. In other Unix/Linux environments I've seen emails from the print daemon when it experienced problems with specific jobs.
Are there other Linux facilities aside from cron and lpd that use email to advise the users of possible issues? Are there ways to secure sendmail or secure alternatives to sendmail? My primary need/desire is to make sure that emails regarding issues on the server get to the appropriate users. Secondary goal would be to have the ability to use mailx to send mail out. There is No need/desire to receive mail from outside.
I'm writing a script that will send an alert email given certain conditions. I have the impression that sendmail is what I need to do that. I just don't know how to use sendmail at all. I assume I have to set it up like a typical mail client so that it has a mail server to log into to send from.
I've looked through the man pages, but I can't find anything in plain English there on how to set it up, or how to use it once it is set up.
Ok so in my /var/log/http/error_log, i'm seeing this error message on the script:
PHP Warning: mail(): Could not execute mail delivery program '/usr/sbin/sendmail -t -i' in /home/account/public_html/collect/add.php on line 18
So, the script i have is very simple, its a webpage that takes in an email address, puts it into a mysql db, and then fires out an email.
Here is the script that its refering to with the error (the orange line). Also, I can run the mail command on the command line seperatly and i get the email fine... I also had this script working on this server before so i know its not a global configuration, just i made some changes without a backup (i know) and now i cant get it working again.
