Ubuntu Servers :: Setup Postfix Mail Server And Courier-imap/pop
Feb 23, 2010
Setup my postfix mail server and courier-imap/pop. My postfix server now is working with tls and saslauthd, I can send/receive email inside my domain as well as outside. However, I need two separate smtp and imap/pop3 server, I mean two machine - one with smtp function and one with imap/pop3 function working together.
I have installed qmail on my 10.04 server (Because I prefer qmail and dont want to use postfix) and I would like to just install courier IMAP/POP server without the Postfix (Or other mail servers).
Is there an apt-get install switch that will install just what I want to install without deps; or at least a way to block unwanted deps from being installed.
I am trying to set up a Mail Server -- Virtual Users with Postfix, PostfixAdmin, Courier, Mailscanner, ClamAV On CentOS 5.5 using this guide. These are the version and softwares I have used till now:-
I'm somewhat familiar with Linux and became pretty decent at installing and configuring packages in Ubuntu. One of the things I was able to do with my tinkering was set up a functioning imap and pop3 mail server using dovecot-postfix. Now I'm experimenting with Slackware to get the feel of another distro, and I noticed that the mail server packages were already installed. On my client computer they can pick up that I have users configured and my mx record is working.
However it is failing to send mail saying that it is failing to relay the e-mail message and that the server responded 5.7.1 which was a problem that I was having in Ubuntu when first configuring the mail server. The fix was to edit the postfix.conf file and adding the localhost name of my server. Does anybody know of the file that I need to edit to make it possible to relay my messages with both pop3 and imap.
I am currently running Ubuntu Server 9.10 and followed this HOWTO on setting up my email server.

Everything seems to work correctly. If I look in the Maildir the emails I send to test are there.
The problem is when I try to sync my email via IMAP from my windows box (on a different network) it doesn't show any of my email nor does it deliver new email. My email app doesn't give any errors nor does the logs on the server.
How can I get it so my email syncs to windows computer? I am sure it is something really small that I am over looking but I can't seem to find it anywhere. I don't know if you need to see any of my config files but I can post them if needed.
I'm running SUSE linux Server version 11. I want to configure mail server with postfix & cyrus-imap. For that, i have read many documents in Internet by i met issues. I'm running DNS in this server & it's ok Now I cannont send mail through command line.
I'm trying to get my server back up to snuff. I'm using Debian Squeeze right now and I'm up and atom with apache, mysql, php, pureftpd, ssh, and I have squirrelmail installed.
My dilemma comes with the mail part of the whole ordeal, Postfix and Courier are installed, have their keys made, and for what I assume, are configured correctly. HOW do I make new virtual users? My domain points to this machine as well as my MX record for mail.mydomain.com.
I need IMAP and POP working. And upon the creation of new email users, will SquirrelMail interface with Postfix and Courier? When I installed SM I set it up for use with Courier.
Does anyone know if there are only personal preferences between the two IMAP servers or does one of a slight advantage over the other? I've used Dovecot only in the past but my package manager loads tons of MySQL libraries with Dovecot which is a problem since that's not authorized on my server right now. I can either install it from source or try another application like Courier.
I've been running Courier IMAP for many years now, but when I added gmail's IMAP to my Outlook I noticed something interesting: when you delete a message, it gets thrown into the trash instantly.
With Courier IMAP (or any other IMAP server, for that matter), when you delete, it first marks it for deletion. Then after you Purge Deleted Messages it either gets rid of them or moves them to trash.
I have a problem relate to posttfix.I want to mirgare postfix mail server to exchange 2010 mail server but I can't do it,u can help me.You can show me have to do configure postfix and exchange how to?
how to install Courier IMAP server and they all say the same thing, but they keep giving me problems.URL... is a link to the page I'm working on.I created the user, edited sudoers manually since I can't effectivly use visudo in the terminal since I don't know how to save. I also made sure that I restarted after I edited it in order to make sure it took effect. I used su compileuser and just logging in as compileuser and opening a terminal. After I made the user and edited that file, I created the directory mentioned and ran the command to create .rpmmacros. After that I got to work on wgetting the files and installing them and what not. The first one compiled and installed and so did the last one. The command "rpmbuild -ta courier-imap4.6.0.tar bz2" would not go though properly. This one I need to run as a non-root user and I've tried using every way possible to be as distant from root as possible, but it still gives me this at the end.
Using the following software: Ubuntu Server 8.04 SquirrelMail 1.4.13 Postfix 2.5.1 Courier 0.59.0 (Courier-IMAP 4.3.1) Apache2 2.2.8
I've installed a mail server per the instructions at [url].
Neither POP nor IMAP test successfully with the user that I just added after following the setup instructions.
This doesn't make any sense. I added the user to the mysql database:
Code:
And after I did that, I ran the postfix reload command. If I try to log in as firstuser@mydomain.com, which is the user I created during the setup and configuration process, it works fine.
I checked the virtual mail account's home folder, and under the mydomain.com folder, I only see a folder for firstuser. I'd create one for testuser manually, but I don't know if that'll work since it seems to contain a particular folder structure of its own.
Is there some other command that I have to run? I don't recall having to do anything additional when setting up firstuser.
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 am administrating a server with CentOS installed. It came with qmail and courier-imap preinstalled, and Plesk.I need to manually add email accounts outside of Plesk, because my 1-domain Plesk license only allows the creation of one email address (yes, it sucks).
When I say add email account I mean creating a new email address, have email for that address be stored in its maildir, and have a corresponding imap (and hipefully also pop3) account that will be able to read that mail. All this with virtual domains.I've already found out how to create the new email addresses for qmail, so that email for the new email address is being delivered correctly. Now I need to create the imap/pop3 accounts for courier.
For the qmail part, I create a folder in in /var/qmail/mailnames/virtualdomain.org/username and a maildir called Maildir inside it. This is how the first mail address was created by Plesk and i'd like to maintain the same structure. As I've said, the qmail part is already working, I need to get the courier-imap part to work. Ideally, it should accept login with both short (i.e. myuser) and long (i.e. myuser@virtualdomain.org) user names.
Currently the only authentication module that is enabled in courier-imap is authpsa, which is Plesk's authentication module.in order to add more authentication modules, do I just need to add them to the authentication module list in /etc/courierimap/imapd, or do I need to reinstall courier-imap with support for such authentication modules? I thought I would only need to add them to the list, but I've noticed that the /usr/lib/courier-imap/authlib/ folder only contains a binary called "authpsa". Does that mean that other authentication modules are not even installed? If so, can I install them without reinstalling courier?
The second question is, what would be the most recommended authentication module that would make it easiest to create new email addresses/accounts from the command line? I need to be able to write a shell scripts capable of creating a new email address with all that is needed, and I'd like to keep this script as simple as possible, so for example I'd avoid mysql-based authentication as it sounds rather complicated. And the last question is, if I do need to reinstall courier-imap, how can I install a package without recompiling it? Will my one existing mailbox keep working?
I setup a qmail on a Debian 5 Lenny server with courier-imap server. I can send mails but cannot receive mails. I altered /etc/init.d/qmail as follows.
I have setup a postfix + courier + squirrelmail email configuration. I can get to the squirrelmail login page and run its test and it said everything was fine. After that I am stuck. What is the username and password or if it is not created, how do I create it?
I setup a postfix mail server. Tested it to make sure it was secure and all seemed good.I sent some test messages and see from the logs that mail is being delivered to the recipient. its only delivering mail to my user's local mbox on the linux server. IMAP appears to have its own mailbox and the two boxes are no linked. I was thinking it was an alias issue however I did at one point have the mailboxes to be the same.... now they are different... Here is the config file.... (I changed the domain names for privacy).
i followed this tutorial to the "T", [URL]. I am not able to login to the mailboxes with squirrelmail, it says "connection dropped by imap server" I used the whole address as a login just like it said to do. I can sucessfully authenticate with outlook express but it throws an error that say's [URL], no such file or directory. i can telnet into it remotely but when i type ehlo [URL] it just keeps showing all the 250 lines and wont let me generate a message.
from what i saw on the comments on the tutorial and googling there are many other people with this problem, however i found no solutions. This is fresh work and i have not touched any config files since finishing the tutorial
In the last week email delivery had slowed down to taking approximately 24 hours and investigation has revealed that there were 45000 emails in the mailqueue. I flushed the mailqueue yesterday but mail delivery is slowing down again because emails are again being queued by the thousand.
The mails are mainly spam sent to ficticious users at a genuine domain hosted on the server.
My setup is running Courier IMAP with Postfix, Spassassin is installed along with Amavisd-new but I just don't understand why this has suddenly become a problem based on my setup not having changed for the last 6 months.
Should these spam emails be being discarded by spamassassin before reaching the mail queue? Are my discard score settings too high (6.9)?
I set up my mail server using the guide here: [URL] I am able to receive mail, I can send mail locally, but I can't send to external addresses. This is in my mail.log: Quote: Jun 30 14:40:43 Server postfix/smtp[10725]: 2FD9322015BF: to=<myemail@gmail.com>, relay=none, delay=1634, delays=1484/0.02/150/0, dsn=4.4.1, status=deferred (connect to alt4.gmail-smtp-in.l.google.com[74.125.65.27]:25: Connection timed out)
The scenario: We have an external server that runs HTTP/DB servers for out shop system. Then, there's our local, in-house infrastructure that runs a.. yeah... Exchange 2010. The shop system on the external server needs to send mails to customers (order confirmations, invoices, etc.). seing as sending them directly through the local MTA (Postfix) would cause mail delivery problems because of reverse DNS issues, i've set the Postfix MTA to act as a satellite to our in-house Exchange Server, so the Exchange sends the mail instead, giving recipient mail servers a valid reverse DNS lookup.
Now, mails sent by the (proprietary, uneditable) shop system are relayed correctly and sent to the target e-mail address. My problem is: Mails not sent by the shop system, but by our own PHP scripts which run on that same external servers, are NOT relayed properly. So the Exchange is fine with the mails sent by the shop system, but not the mails sent by our scripts. This is what i get in the mail.log: The successfully relayed mail sent by the shop system:
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 want to setup an intranet mail server as a project. I tried to go through various forums but could not get a satisfactory model. My sceme of things is as follows:The server a virtual machine is after a router which has a built in dhcp server. Prefer to use sendmail but postfix ok client machines should be able to access the mail on evolution/thunderbird or web access using squirrelmail.Mail will not be relayed to anybody outside the intranet.
Im looking for a way to block emails that come into the mail server for users that are no longer on the domain. I see a lot of messages in the maillog for emails coming in for people that are no longer active users on the domain.
setup:
Using spamassassin if that matters.
Using Active Directory on a windows server.
I found postfix uses this "reject_unknown_recipient_domain" in /etc/postfix/main.cf but I am unsure where this would be used in courier.
Ive seen some hints here. But not sure how to adapt this for domain users.
so i set out to change the default smtp port the server uses because my ISP blocks port 25 and i need the email to work in outlook. this morning i could receive email, but not send it. so i did some research and thought that i needed to edit the master.cf file in /etc/postfix/ by commenting out this line: smtp inet n - n - - smtpd -oand replace it with587 inet n - n - - smtpd (587 being the port i want to use)somewhere along the lines postfix server stopped running and now i cannot get it to start.if i try using SSH it crashes immediately and if i restart it in simple control panel nothing happens
This is the current setup that we have: We have approx 20 clients who pay us to send out a type of e-mail called an E-Blast to their customers. We currently are using 5 Microsoft Windows Virtual Servers to do this. The problem is that those machines are starting to break down. There are times that it will take Microsoft Windows approx 9-10 hours to complete 1 job. This is way too long. We want to move away from Microsoft Windows for this particular type of job as it seems there are more customers who are wanting to use this type of advertising.
It seems that using a Linux Server "Command Line or Shell" environment would be the best way to go as there is no GUI like Windows. Since there is just text...that is something that would/should process very, very quickly.
I am in the process of setting up a new SMTP outbound mail server. This is the current software & configuration (what is installed on this new machine):
All of the customer data (Names, E-Mail Addresses, etc that these e-mails are going to) are currently loaded in a Microsoft SQL Database.
My machine that I am using is plugged into the DMZ. I have 1 ip address for the 1 network card. I have also added/bound 4 more ip addresses to that network card.
I have configured Postfix for Multiple IP Addresses.
I can, from the command line, send successful test e-mails and receive them in my personal account.
As far as I know everything is setup correctly. I can and will post requested information so that it can be verified that everything is setup correctly.
Here are a couple of my questions:
Ensure that I have my Network / Interfaces file and my Postfix's Master.cf/Main.cf files setup correctly?
How can I setup this server to be an Outbound SMTP server and get it to use all 5 of the IP Addresses to send these e-mails quickly?
What can I use to check and ensure that this server is in fact sending out emails on all 5 IP
Addresses (I heard that there is a program named "Postal" that may help in determing this).
