Server :: Unsure Of Exim Configuration - Accepts Mail From Users On Multiple Domains To Pass On To The Outside World
Dec 29, 2010
I'm in the process of starting a migration from an old postfix server to nice shiney new exim server however there are a few things i'm really not clear on and i'm hoping that some one here could point me in the correct direction. Okay the postfix server at the moment does the follwoing ( i'll try and keep this simple ):
* accepts incoming mail for users on multiple domains and puts the mail in the users mailbox ( external -> internal )
*accepts mail from users on multiple domains to pass on to the outside world ( internal -> external )
Obviously the POP and Imap functions are handled by other daemons.. I'd like to replicate this sort of setup on the new exim box, however the guides i can find only help with configuring the exim system for incoming mails ( external -> internal ) for multiple domains and i cant seem to find a guide that would indicate how to do both ( internal -> external and external -> internal ) on one box. I'm guessing i may have to do some sort of auth to get exim to accept and then handle the internal -> external side of things?
Two exchange servers internally. One is setup for example.com (192.168.1.10) and the other is setup for example2.com (192.168.1.20) Both are behind a single public IP.
I want to use postfix to sit in front of the two exchange servers. Postfix will accept mail for both domains and relay to the appropriate server. I have postfix installed with only defaults at this point.
I'm running a server with two sites which both need to be able to send emails. Currently I have Postfix set up to send email via Google Apps. This works fine, but Google's servers ignore the From: address I specify and substitute the one I logged in with. Is there a way to make Postfix log into Google Apps with a different username based on what site the email is coming from? The server does not recieve any mail itself; Google recieves it and we have it set to forward it to the appropriate person's real email address. I'm only worried about sending mail.
(Postfix is not a requirement here, so if there's another mailer that can do this better, I'm open to ideas. However, sending email directly from the server isn't an option as it's a residential IP address and blocked by most of the big email providers.)
Im moving all my websites on a dedicated box. I had a cpanel hosting account, and now moving to a terminal and ssh system.I need some advice on choosing my mail setup. I need POP, SMTP, with multiple domains, as host for a few clients.I would like the most simple version.The server will only send +- 100 mails / day.I currently running Ubuntu Linux 10.04.
I have recently setup an Ubuntu 10.04 Minimal x64 Server. I plan on setting it up as a mail server. I need a secure server, that has spam prevention on it. Im setting up around 50 domains and would like a web based control panel. What is the most secure mail server, that i can setup for multiple domains?
I cannot get exim4 to actually deliver any "local delivery only; not on a network".But whatever I do in the config, all mail gets frozen with entries in the log file like:"root@empty R=nonlocal: Mailing to remote domains not supported"Maybe the problem is that there is no fqdn for the computer (and will never be). How can I enable local mail delivery?
I run a mailserver and this is bothering me quite abit. Being going on for about a month now. Running exim4 and dovecot with exim4u. This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

This is a copy of the message, including all the headers.

I run OSX on my everyday computer so this is not me sending out stuff since the above mail says Microsoft Outlook express has sent it (?) Running a Debian Squeeze server. And I really dont get any other spam due to exim4u setup and spamassasin.
I'm trying to follow the exim documentation to allow suffixes on mailboxes for all users. For example, if user@domain is a mailbox, I want all mail directed to user-*@domain to be delivered user@domain. I've got the split-config-files option and have edited /etc/exim4/conf.d/router/600 to include local_part_suffix lines as follows:
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.
We moved over from Cpanel using Exim. I was wondering if anyone knew of way to convert the mail so when a user logs in they get to all their mail in their folders. I notice exim has a ton of folders while postfix creates files that act like folders which contain all the emails. I sent up 1 of the emails into the our mail folder that was created by Exim and it can be Subscribed to in Outlook with imap but the emails inside doesn't show up. They both appear as text files so I don't know what the difference is.
Let me start off by saying I am experienced with computers, though my knowledge of Linux and networking is limited. I've just recently started setting up a Ubuntu 10.04 server to be a SMTP server. I've followed this guide by the letter: [URL] What I've attempted, to test the server, is the following:
telnet localhost 25 ehlo localhost
(this returns all the desired information) I then do a MAIL FROM my domain which is accepted, and try to do a RCPT TO an external mail server (gmail) to test sending an email. I am then told 'Relay Access Denied'. I'm sure that there's something fundamental that I'm either not understanding or not doing correctly. I simply want an SMTP server that can send to other domains. What do I need to do?
I have a Fedora 10 machine that I want to setup to send email. However I don't want it to be a full blown SMTP setup.What I am looking to achieve is when something sends email from the local machine (e.g. from cron) to an address I want it to use an MTA on the local machine which will then connect to, and authenticate with, my e-mail providers SMTP server this will then take care of actually sending the e-mail.I don't want, or need, to setup a full blown SMTP service (i.e. only the local machine should be able to use it) so sendmail seems a bit over the top for my needs. Nor do I want to mess about with MX records (am I right in thinking this will mean I have to manage all mail for my domain?).
i was asking how to build a CentOS Exim mail server, & gaurantee that all mail messages will be delivered to hotmail inbox ??hotmail said that it will only accept 500 simultanuos connections (=500 messages) to its mail servers from only one IP address, so is there an exim options that i can use to limit messages that sent through the mail server to hotmail to be sent as 500 messages then send another 500 & so on
I am trying to do something really simple with Exim. I have two machine connected together via a hub. They can ping each other. They each are running openSuse 11.2 and have Exim installed. On each machine from the command line in start Exim as a daemon by typing: sudo /usr/sbin/exim -bd -d and each machine runs through some output and sits there "Listening". Then on either machine I try to send a mail message of the form mail
(or mailx) <user>@<other node> some text EOT
and absolutly nothing happens! I must be doing something wrong or daft which is very basic, but I have searched all over and cannot get it to work.
My employer has started the process of certification with Return Path, and I've been roped in to setting up DKIM, SPF, SenderID etc. so that we are compliant with the certification requirements. Our current e-mail server is qmail, and I'm really not too keen on messing about with the configuration files there. As a safer alternative, I've decided to set up a smarthost relay that only does the DKIM signing. I tried and gave up on Postfix - struggled with understanding the configuration files - and eventually found Exim.
Now, I've got the relaying working perfectly so far. I am NOT running an open relay, my smarthost is configured to only accept SMTP connections from the existing mailserver, and not publicly accessible anyway. The problem I'm having is figuring out exactly where in exim's configuration file I am supposed to configure the DKIM signing options. I've read the official exim documentation and I'm fairly sure about the syntax, I just can't figure out where the options go.
I am going to try and replace our crappy Windows/imail server with a new ubuntu 10.04 LTS based machine. It will end up with about 400 domains on it with around 3000 users total. 96% of the domains have very light use. 4% of the domains have heavy use but do not send any bulk mail.
Can someone here recommend a mail server software package that would be easy to administrate and easy to backup/replicate? All we need is POP with webmail. We do not need IMAP or want any group/collaborative functions.
What do you usually use for anti-spam on a linux mail server? We want to keep it all open source if possible.
For hardware we are looking at an HP DL360 G5 with dual Xeons, 4G of ram, and the P400 controller with 6 SAS 15k drives. Do you think a server like this will be able to handle the mail on linux? Volume is around 400k messages a day inbound with about 10% being legit/90% being spam. The server will be dedicated to mail hosting and will not host websites.
set no bouncemail set postmaster email@example.com set logfile /var/log/fetchmail poll pop.teledataict.com protocol pop3 localdomains dot.com.gh archive dot.com.gh no dns
envelope X-Envelope-To: qvirtual dot.com.gh user "firstname.lastname@example.org" there pass "mail" is * here forcecr nokeep flush dropdelivered fetchall
This works perfectly as I want. But right now, what I want is, I want fetchmail to download mails for more than one or several accounts in different domains and different pop servers. How can I improve this rc file to accomplish my task?
Is it possible to add/join my Linux Suse 11.3 server with 2 domains ? I know I can do that with Windows PC, but I never try that with my Linux box. FYI, my Linux server is already joined with a domain, now I want to join my box with another domain and I don't want to take it off the current joined domain.
I am setting up a Postfix MTA that will be only sending mail for 10 different domains. We have other servers that will be receiving the mail for the domains so I only need to set up for sending on Postfix.
What my issue is I am trying to configure Postfix so that when it sends mail the header shows what domain the mail came from and not the domain the Postfix server is set to. For example....
When I send mail from domain2.com I want it to show in the header it was sent from domain2.com and not from domain1.com. What do I need to set in postfix so that this happens? Right now no matter what domain the mail is from the header always shows the server domain and I can't have that.
I am using squid 3.1.12 as a proxy cache. All the requests initially land on a Apache server which acts as a reverse proxy server, the Apache redirects some URLs based on the context to Squid server. This Squid server based on the URL needs to forward the request to the specific tomcat server where the application is deployed. I am able to configure just for one application but how do I configure multiple tomcat servers(each tomcat having different application deployed on it). Squid needs to redirect based on the URL.In Squid.conf I made the following changes
Here Squid is deployed on my host [URL], Apache redirects any URLS with the context 'ABC' or 'DEF' to squid. Squid needs to redirect it to the individual hosts thats [URL] or [URL] based on the URL. I have commented the entry for DEF in my squid.conf as it was not working. But it does work for any URLs with ABC as the context.
I've got a request from one of my company's subsidiaries to block all incoming and outgoing mail for a group of users. I've read up some guides on access.db and I know how to do that, but now they want to allow these users to receive emails from a few select domains, and block the rest. To summarize:
1) Block all incoming and outgoing email to users in team A, except mail from [URL] 2) All other users can receive and send mail from/to any domain.
I work for a college with many departments. I'd like to just deploy one LDAP/krb5 server (plus slave replicas) to authenticate all users in all departmentsIs it possible to do this?The proposed DNs for the departments matches what is done for NIS now.If anyone has any pointers or URLs that describe how to properly do this.
I have configured postfix to send/receive mail from/to for two domains we manage. [URL] and [URL] Most of the cases there is no issue sending out or receiving emails. However, a few users of domainY.com complained that their senders were not able to sent them email. after much investigation, we started thinking that the mailserver failed to send us email may the failing on doing a SMTP Banner issue.
Is there anyone who knows how to deal with this SMTP banner issue with multiple domain. We want different SMTP banner when doing EHLO on different server.
