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:-
[Code]....
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.

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 have setup postfix and postfixadmin on a CentOS 5.5 server and the install appears to be ready to go. I have never used postfix and postfixadmin and I am having a hard time finding any documentation on how to setup and administer the postfix server with Postfixadmin. This is simply a test and alerting server and will not be hosting user mailboxes. I am only looking for the basics I am not going to need to setup anything complex

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.
I configured my server to have the virtual mail authenticated and stored through mysql DB.Now the authentication works, but then I got the dreaded -ERR chdir error.After research and testing for ohurs I finally got it working on ONE account after I created the maildir with maildirmake.Now I am able to login and "list" messages, but nothing else. When I use postfixadmin to setup a new user, the maildir does not get created so I have the same problem.I'm trying to troubleshoot what is happening.Here are the relevant config files:
/etc/postfix/main.cf
Code:
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no[code].....
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 just recently purchased a vs from a company and i am trying to set up a web site on it with kloxo and set up the mail for it upon setting up the mail settings it says:
"It is very essential that you set the my name to a properly resolvable hostname, since otherwise, many public mailservers like hotmail will reject mails from your server"
Now this is my first time setting up a vs before i have set up linux vm's to get email access but that was about a year ago.
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

I can send mail when I am root to the other user on my (same) machine both when in command line (mail command) and on Graphical mail client (Kmail ) but the user (sam) cannot send mail to the root account on either interfaces.
I followed the postfix configuration settings on John_Wiley_-_Redhat_Linux_Networking_and_System_Administration_3rd_Edition.
I have a problem concerning the vacation(auto response). I got a mailserver(smtp.mydomain.com), pop3/imap-server(mail.mydomain.com) webserver(www.mydomain.com, with postfixadmin on it). I use Debian 5.0 So it's like this, I receive mail to smtp.mydomain.com, it get checked for spam with amavisd-maia(Maia Mailguard), then delivered to the pop3/imap-server. I'm guessing there's something wrong with my postfix setup. I activate auto response for my account, when I get a mail it says this at smtp.mydomain.com:

I was following the above guide to get a mail server up and running. The major difference in it all is the fact that my server is running i686, but I compensated for that easily, just a difference in folder/RPM names. [URL]. Otherwise I followed it to a "T." Everything seemed to go smoothly, no trips or falls until the very end.
After installing squirrelmail and trying to login on admin@withfrosted.com returns ERROR:
Connection dropped by IMAP server.
Uncle google tells me to run this command because SELinux is overzealous:
setsebool -P httpd_can_network_connect=1
And that works, and I thought I was home free. However, after that, I'm presented with a new error. However, google told me to send an email to create the mailbox because it wasn't there, yet. So I send a test email on over, but that fails, and so does mailx. Next I created /home/vmail/withfrosted.com/admin while logged into the vmail user for proper permissions. Squirrelmail now logs into the mail box but gives me yet another new error, in which I am now stuck on:
ERROR:
ERROR: Could not complete request.
Query: SELECT "INBOX"
Reason Given: Unable to open this mailbox.
As a summary, because I'm all over the place, here:
1. Can't view the mailbox via Squirrelmail.
2. Can't receive email, tried with mailx and a test email from gmail.
Regarding #2, the gmail test email, from the maillog:

I've setup my server by following a ton of goods, and it seems to work ok, but I need to start using my server for email in order to receive orders placed via my website. I've followed this guide - [URL] I followed the steps above, and tested the mail server via telnet, and all seemed to be ok. I tried sending an email via Squirrelmail, from cs@thinclientwarehouse.co.uk TO my working email simon@c1systems.co.uk, but the server returned with the following message:

View 5 Replies View RelatedI have to administer a few mail servers, a mail log server, 4 nameservers and a web server -all running on Centos 5 server distributions. Now I have a task: to avoid accidental crashes on the production servers while installing updates, my boss asked me to do clones (these clones will all be VMware virtual machines) of the servers (EXCLUDING the actual e-mails and mail log contents) and then to run those clones on VMWare Server. This way, first I will install and test updates on the clones and - if they will be running without crashes - I will apply the updates on the real production servers themselves. I have already installed VMWare Server 2.0 I have a few questions:
- How do I build the virtual machines to exclude the actual mail files and mail logs? Can I use VMware Converter for this purpose, or do I have to use another program?
- How do I actually do this cloning? Is there a tutorial on how to do this?
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.
can i just copy/backup postfix mail queues in /var/spool/postfix and paste that folder back in after i done migrating all users and mails to a new mailserver?
View 3 Replies View RelatedI tried to setup a Postfix system as VM Guest, in a single file image. So I want to store the mails on another hosts throught NFS mount. I got various errors when Postfix try to write to the NFS share. Anyone knows what's the correct setup for this? like file permission on the NFS?
View 1 Replies View Relatedi 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
is there a rpm available for postfixadmin for centos 5? i cant seem to locate it.

Things I have tried to fix this problem, but didn't work.
1) Stopped postfix, uninstalled and reinstalled.
2) Did a complete filesystem relabel with a touch /.autorelabel and reboot.
3) Did a restorecon -F -R on /etc/postfix, /var/spool/postfix and /usr/sbin/post*
Nothing above has worked and have no idea why with selinux disabled postfix works and with it on it fails.

I'm new here and I'm sure this question has been thrown around a lot but I just couldn't find a solution. I have a networking website I've setup and we need to send notification mails to our members depending on activity related to their profiles(messages, comments etc).We are hosting the site on Centos5.6 with VirtualMin and are using Postfix as our MTA. We also use google apps for email on the site. Heres the problem, the mails go through for some gmail users but more often than not, they end up in gmail,hotmail and yahoo spam.We've setup the appropriate SPF codes on the server, DKIM and rDNS works fine.v=spf1 ip4:xx.xx.xx.xx a mx include:_spf.google.com ~all Below is a sample email that goes directly into gmail spam. I've replaced the actual values with dummy text (Ip, Domain etc)

i currently installed centos 5.3 with postfix. My old server is centos 4.5 final / new 5.3 final. Old server has sendmail / new has postfix. how can i transfer all the mail and settings from the old to the new? also, the old mail server is mail.xxx.xxx and for testing purposes i named the new mail server mail2.xxx.xxx.
when i an ready to put it into production, the new server will need to be mail.xxx.xxx and the old removed from the system. How do i go about changing the name and making sure everything comes out correct?
I have postfix setup right now and it's relying mail to our Exchange server fine. What i would like to do though is have postfix save the email that gets passed through so that if a manager deletes an email, it's easy to look through by date and find the email he's looking for. Well, I'm thinking it would be a lot easier then having to need to pull out the backup tape and try to recover one email. Does anyone know whether I would be able to accomplish this?
