Server :: Spamassassin Amavisd Reject Unknown User Before Process Mail?
Mar 23, 2010
start working with SA+Amavis+clamd+postfix+dovecot.will be my filter:spamassassin+amavisd-new+clamd. 1 Server will be my mail server: postfix+dovecot. Like u see, the emails from the outside reach first the filter, latter the mailbox. Now, I have seen in my log files, that if I receive a email to a "unknown user", the filter doesn't detect this and process the email and send it to the mail server. Exist a way to setup the filter to first check if the user exist and them apply all hard work and latter send the email to the mail server

I followed this how to document [URL] to install postfix, Amavisd, SpamAssassin and ClamAV. My postfix installation is working fine and I can send and receive emails fine. However, it looks like SpamAssassin is not catching any emails. Emails do get passed over to Amavisd as I can see in the logs but ALL Messages comes out CLEAN without being tagged as spam.
As per the document, I did test by sending a test virus email
sendmail -i your-address@example.com < sample-virus-simple.txt.
This is caught and NOT let through so ClamAV is ok but when i send
sendmail -i your-address@example.com < sample-spam-GTUBE-junk.txt
it does get delievered without being detected as SPAM or tagged as SPAM.
As I said, I have followed the documentation dot by dot and hence do not have spamassassin starting up as a service but i guess amavisd starts it within itself as a module.
Also, my postfix version is the one that supports mysql virtual tables which I got from rpmforge.

I configured a mail server using Squeeze's latest packages with Posfix + Amavisd-new + Clamav + Spamassassin, but apparently the latter is not using the system configuration files, and I cannot figure out why.Running amavis in debug mode I get the following:
# /etc/init.d/amavis debug
Trying to run amavisd-new in debug mode...

I have this strange error - I switched from postfix 2.6.5 to 2.8.2 and I some mailservers cannot send mail to me. One of them was some sendmail server. I have virtual alias maps in mysql. It works fine for almost all server that are sending mail to me, but some of them seems to send mails as user@FQDN instead of user@virtualdomain my machine name is x49.tvujweb.cz, and mz email is kamil.horky@servis-it.net but in server logs is that user kamil.horky@x49.tvujweb.cz cannot be found in virtual alias maps.
here is my postconf:
Code:
2bounce_notice_recipient = postmaster
access_map_defer_code = 450
access_map_reject_code = 554
address_verify_cache_cleanup_interval = 12h

I'm having a problem whereby I'm able to send mail to a mailbox from several different email addresses and SMTP servers (gmail, RoadRunner broadband), but I'm unable to send mail to the same address from one particular account, the SMTP server for which runs on a mediaTemple (dv) 3.0 box with CentOS 5 Final.I've spent a full workday on the forums, trying to troubleshoot the issue, and I'm running out of ideas.The server on which I'm having the mail processing problem is a mediaTemple (ve) running Ubuntu 10.04 x64 (Linux 2.6.18-028stab070.7 #1 SMP Fri Oct 1 13:53:00 MSD 2010 x86_64 GNU/Linux), with ISPConfig 3. Here's how I setup the mail-related aspects of the Ubuntu box:
Code:
apt-get install postfix postfix-mysql postfix-doc mysql-client mysql-server openssl getmail4 rkhunter binutils dovecot-imapd dovecot-pop3d

I have a mail server taking care of mail for my 4 domains; the first is used for virtually all mail, the second rarely used anymore, the third is virtually 100% spam the past year(?), and the fourth isn't in use (and never has been, so no spam). What I'd like to do is to reject all mail to the third domain. Right now this is what I get (I tried to send to a nonexistent address from gmail):
[code]....
Since my username (xyz@) is the same for all domains, I could (or so I hope) change the reject message to give a hint to replace [URL] with [URL] and try again.

Brand new to Linux. Sort of got thrown in front of the bus if you know what I mean. The company I work for has a Linux server running CentOS 5.4 Company uses Linux for their Email, FTP and Web Server. Have been here a few years dabbling in and out of Linux and now that the old Admin has left the company.....I need to learn it ASAP. The server has run pretty solid until today.
The email server runs SendMail and SpamAssasin. Received lots of complaints today regarding extra SPAM. Noticed that SpamAssassin was not running. Tried to restart it through the WebMin tools and got the following error: Starting spamd: child process [3956] exited or timed out without signaling production of a PID file: exit 255 at /usr/bin/spamd line 2588.

I'm using postfix on Ubuntu 9.10 and all I need is to occasionally send automated emails from perl or php scripts when data processing errors occur. In other words, I want to reject any connection attempts from remote clients and otherwise allow nothing except outgoing emails from one particular account.f I add this line to the default main.cf, will it do the trick or is it more complicated?
Code:
smtpd_sender_restrictions reject

I am trying to built a mailserver using Sendmail + cyrus + amavisd + TLS authentication. All programs used are the latest versions shipped with OpenSUSE 11.4 I have set-up successfully sendmail+cyrus and I can send e-mail anywhere without a problem using authentication. But when I try to integrate amavisd-milter mail delivery hangs at 63% and the following message appears in /var/log/mail
[code]....
I have also uninstall all involved programs, deleted all conf files and re-installed them but alas without any success. The same configuration was used at least once with almost all previous SuSE/openSUSE versions since 1998.

I've setup postfix using mysql tables and all works except for sending to an alias. The mysql logs show that postfix is only looking at the mailbox table for where to deliver the mail for the alias. However it is not looking in the virtual alias maps table. There are no complaints from postfix on startup to indicate that there is anything wrong, and if I send to a virtual domain listed as a relay on the server it does look up the virtual alias table... even though the domain is not hosted on the server....
So the question I have is where to look next? The mysql log shows the expected lookups from postfix EXCEPT for the virtual alias map queries.... why would it not be checking the table? Since it is not looking up the virtual alias it bounces the addresses back to sender complaining that the user doesn't exist... It does deliver to a virtal mailbox, however again it never checks the vitual alias table.... so it only delivers since there's a mailbox for it rather than needing an alias...

I have a Fedora box running a domain and a sub domain. It also is the mail server running Postfix and Dovecot. I have created a new user account in the Virtual Alias.conf file and run postfix reload.
"e.g [URL] admin_company"
This new account can send mail internally and externally but cannot receive mail internally and externally.
The error message internally is: 5.1.1 <admin@threadneedle.com.pg>: Recipient address rejected: User unknown in virtual alias table

I work for a university institute and administrate its servers "incidently". Currently I am putting some work into our mail server configuration (sendmail 8.13.1 with amavisd-new-2.6.4). Recently I got amavis to verify DKIM signed mails. Now my plan was to sign outgoing Emails ourselves. This is what I have done (I replaced some names for privacy reasons):
I created a private key:
Code:
/usr/local/amavisd/amavisd genrsa /var/dkim/SEL1_DKIMkey.pem
Changed permissions for the user running amavis:
Code:
chown -R vscan.vscan /var/dkim/ && chmod -R 700 /var/dkim
Editet my /etc/amavisd.conf:
[Code]....
Send Testmails to sa-test@sendmail.net and check-auth@verifier.port25.com . They automatically create answer mails considering signature information.
Send emails to my external account at some other provider.
The problem is that amavis is not signing the mails. Both automatic test emails reported, that the mail had not been signed. The mail to my external account also did not contain any DKIM information.
"My" system:
Code:
# uname -r & cat /etc/issue
2.6.9-89.0.11.ELsmp
Red Hat Enterprise Linux AS release 4 (Nahant Update 8)

I have postfix setup with amavisd and I tried to send myself an email with the eicar file however it lets the email go through to my inbox. When I restart the amavisd service, there are no errors in the log and it finds all the decoders for different file types and I also see this come up:
Feb 8 14:45:44 Mailgate amavis[3116]: Using primary internal av scanner code for ClamAV-clamd
Feb 8 14:45:44 Mailgate amavis[3116]: Found secondary av scanner ClamAV-clamscan at /usr/bin/clamscan
Everything seems to work but it doesn't scan the file for viruses. Also, I've double and triple checked and my amavisd.conf file doesn't have the option enabled to bypass virus scanning.

I'm migrating a mailserver from an old to a new mailserver. The new mailserver is based on ISPConfig 3.0.6.1. I would like to migrate what spamassassin learnt in the past from the old mailserver to the new one. Now the question:
- The 2 spamassassin versions are different. Is it a problem?
- Can I just migrate the database with this commands???
Code:
sa-learn --backup > sadb.bkp
sa-learn --restore ./sadb.bkp
-how to migrate SpamAssasins Auto White List and all others SpamAssassins databases?
