Ubuntu Servers :: Courier - Postfix - ClamAV - Spamassassin And Amavis Setup
May 4, 2010
I am currently running Ubuntu Server 9.10 and followed this HOWTO on setting up my email server.
[url]
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 can send emails to local accounts but not out to the world. Here are the refrences I used to set things up.
[URL]
I was able to send and receive after the "basic" setup. I added amavis-new and I am pretty sure that it stopped working then. (late nights, lots of changes/tries not 100% sure any more) Went back to basics trying to send a test email from telnet (on the server).
Code:
mail:~# telnet mail.my-server.com 25
Trying 216.240.35.89...
Connected to mail.my-server.com.

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)?

im using postfix with amavis and spamassassin as spam/virus filtering and its working great.However, i get a "lot"(1-5/day) of "bad header" messages beeing quarantined by the server. And most of theese bad headers are false positives that i manually have to deliver to the correct mailbox.How can i make amavis/spamassassin deliver bad header messages to the correct mailbox and not place them in quarantine?Theese are my amavis settings. (which file is used, 20-debian or 21-ubuntu??)

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 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?

After the EOL of 0.94 clamav, I removed it stopped amavisd from having my mail scanned, and installed the new version of clamav 0.96.
But, when I try to start amavisd and send a test mail these bunch of errors appears:
[code]....
I've read some posts that had no reply, someone tried to telnet to 127.0.0.1:3110 "the default port of clamd". I tried that but I got connection refused.

I have a dedicated server which is running CentOS release 5.5
I'm still learning this as I go, but, frustrated at the amount of spam I was getting, I decided to install the Qmail scanner.
I followed the instructions here, all of which seemed to go well.

However, now when I try to send mail I am getting the following error:
The mail server responded: qq temporary problem (#4.3.0).

block incoming email within either postfix or spamassassin when the sender equals the recipient. The manner in which our mail infrastructure is set up would preclude this from happening. Granted, we do have outside vendors that spoof our domain so we have to allow emails in with our domain as the sender/from. The vendors do not, however, utilize the same sender/recipient when sending emails.

I have Postfix and Spamassassin setup on Ubuntu Server 9.10. The mail is working perfectly. Spamassassin is correctly marking messages as spam. My problem is with the milter and procmail. On past servers I was able to reject spam based on score via the spamass-milter. For whatever reason I can not get it to work. I have also tried with procmail, again, it does not work. Here are the relative lines in their respective config files:

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

I have a problem setting up Postfix on my home (behind Router/firewall) Ubuntu driven server, I have been trying for days now with no luck. All I would like to do is use the server to send mail (MTA). So while installing I configured it as a satellite system.
file:
/etc/postfix/main.cf
settings:
myhostname = mail.example.com
mydomain = example.com
alias_maps = hash:/etc/aliases
[code]....
I'm getting a 553 From address not verified. I have tried what it suggested from the URL link, but it still doesn't work.

I installed Postfix, Amavis-new + Spamassassin + Clamav, Dovecot, and SquirrelMail today, using the Ubuntu guides for each. I have 10.04 LTS Server. My PHP scripts can send email, but when I tried to log into Squirrelmail, I couldn't. Here is what my error log produced (the server name and user name have been changed) :
Code:
myserver dovecot: imap-login: Login: user=<username>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured
myserver dovecot: IMAP(username): opendir(/home/username/Maildir) failed: Permission

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].....

I'm trying to setup postfix (or exim, I don't mind which), so I can move away my last remaining PC from Windows.I've tinkered with Postfix for good part of a month and I can get it to accept emails using SMTP and post them to a virtual mailbox based on MySQL tables. And it rejects mail addressed to local email addresses that it can't find in the table.
First question (or problem.) I've set up Postfix to relay email it cannot deliver locally such as is the case when you send out an email. My remote host requires authentication. How can I set this up?
Second question: I want to force my clients to use either AUTH, TLS or SSL, and not allow anonymous connections (to prevent an open relay server.) How do I set that up without interfering with the smarthost setting? The smarthost login is not one of my clients, it's a pre-determined login and password that is solely used for the email relaying aspect.

make install then i got this error: postfix: fatal: chdir(/usr/libexec/postfix): No such file or directory make: *** [install] Error 1 I don't understand why it's checking the usr/libexec folder for the daemons although I've set the folder to /opt/product/postfix-2.6.5/libexec in the makefile.

I have two servers complaining about ClamAV being outdated:
WARNING: Your ClamAV installation is OUTDATED!
WARNING: Local version: 0.96.1 Recommended version: 0.96.3
Doing an aptitude update says I don't have to upgrade anything. Why is this? Must ClamAV be updated manually?

way to remove open-whois.org as an rbl from /usr/share/spamassassin/50_scores.cf/usr/share/spamassassin/72_active.cfIt's creating a lot of false positives on a mail server i am using with ubuntu. i noticed only ubuntu lucid is using updated spamassassin 3.3.1 and all others are using 3.2.5i was on spamassassin's website and noticed this issue has been resolved on spamassassin 3.3.1 but not 3.2.5i tried looking in those files but they are too complicated for me to understand.i am assuming they manually have to be removed.can anyone help with the open-whois.org rbl removal from mail servers as it is currently squatted and creating false positives?

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 have so far: installed and configured postfix, installed courier, installed MySQL and SASL. mostly following a guide on [URL]
When I want to login via POP3 with a user from the MySQL database, authentication fails.
The mail.log file contains the followiung error:
Nov 25 18:47:55 asmahan pop3d: Disconnected, ip=[::ffff:10.11.39.33]
Nov 25 18:48:05 asmahan pop3d: Connection, ip=[::ffff:10.11.39.33]
Nov 25 18:48:16 asmahan pop3d: LOGIN FAILED, user=john, ip=[::ffff:10.11.39.33]
The problem only occurs when I try to login via POP3. I can send emails via SMTP using the same account without any problems.

Still trying to get that elusive simple mail server. Have install Centos 5 (20 time!) and updated software. Have got the system to see www and now about to do the mailserver thing. One of the first steps is to install Clamav yet this does not show on the package list for the program add delete gui. Tried yum install clamav and got message back that it wasn't available.
Google advises that I must first install rpmforge but at the same time has a warning from the maker of yum that this is dangerous to do Clamav is clearly a very popular antivirus scanner yet Centos 5 does not include it or allow you to install it?

Code:
groupadd -g 5000 vmail
useradd -g vmail -u 5000 vmail -d /home/vmail -m
