Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 9.10)

[marmellata]

Hello, following the above HowTo I was able to set up a postfix mail server. However I have some doubts about spam filtering (amavisd-new, SpamAssassin and ClamAVis) is actually working. Is there a way to be sure they are working? do I also have to port forwarding some other ports on my router in addition to port 25 ?
The last question is.. do you have an idea why other mail servers always put mail coming from my server in spam folder ?

Thanks in advance forr your support

You should check your mail log and the email headers.

Port 110 for POP3, port 143 for IMAP, port 993 for IMAPS and port 995 for POP3S.

Please check if your server is blacklisted: http://mxtoolbox.com/blacklists.aspx

Thanks for your answer as always.

You should check your mail log and the email headers.

In squirrelmail looking at email headers it seems to be amavisd is working:
...
X-Virus-Scanned: Debian amavisd-new at mx2.sialpe.com
Received: from mx2.sialpe.com ([127.0.0.1])
by localhost (mx.sialpe.com [127.0.0.1]) (amavisd-new, port 10024)
with ESMTP id kKkDY7h55hi5 for <g.parlato@sialpe.com>;
Sun, 3 Jan 2010 19:12:40 +0100 (CET)
...
in mail log what should I see? cause I cant see anything about spam filtering process

Port 110 for POP3, port 143 for IMAP, port 993 for IMAPS and port 995 for POP3S.

amavisd 10024 port?

Sorry but sending from a different mail (baboda@cheapnet.it) to my inside mail (g.parlato@sialpe.com) actually I've found amavisd works:

No, you don't need to open that port as it is accessed only from localhost.

The logging is done by amavisd:

Jan 3 20:14:11 mx amavis[1428]: (01428-04) Passed CLEAN, [87.238.28.102] [80.67.127.56] <baboda@cheapnet.it> -> <g.parlato@sialpe.com>, Message-ID: <99A8F300EA854206A2A7B92DEABADF4C@marmellataLapt >, mail_id: Znynqx7wTHmW, Hits: 3.384, size: 1572, queued_as: A5A31235CD, 7143 ms
