Problem with Mailman and Postfix

N

Nokobon

Hello everyone,

I just installed mailman on a FreeBSD 5.2.1 Server using Postfix as mailserver.

Now I am able to create new mailinglists and subscribe to them.
But when I want to post to the list nothing happens.

I think it's a problem with Postfix, as I found this in /var/log/maillog (domains and ip's modified):

Code: 
postfix/smtpd[35957]: connect from *.server4you.de[62.75.*.*]

me@my_address.de: the subscribed user, posting to the list

It seems, that Postfix is blocking the mail as Spam?

I don't know much about Postfix and have no idea how to fix this.
So I'd be really happy if anyone can help!

Thanks in advance,

Nokobon
 
It is amavis who is blocking the message. Try to post the content of spam-pAZzw-y6CZZf.gz (it is located in the quarantine directory).
 
Curiously I didn't found exactly that file in the quarantine-directory, but this one also belongs to a mail I wrote to the mailinglist:

You are kinda brave. Tagging with score 4 and killing with score 5 ?

Code: 
X-Spam-Status: Yes, score=8.907 tag=2 tag2=4 kill=5 tests=[BAYES_99=3.5,
        FH_DATE_PAST_20XX=3.188, TVD_SPACE_RATIO=2.219] autolearn=no

First of all, Bayes is ABSOLUTELY sure, this is spam and that is wrong. How did you train it ? Next, your Spamassassin version contains a bug because of which you received extra 3.188 points, read more here. Finally, TVD_SPACE_RATIO is triggered, because your test message is too short (and has no spaces well ;)). Fix the Spamassassin bug, retrain your Bayes and I think you should rise the scores.

Thank you, hydra!
I don't really unterstand everything you wrote, as I never dealed with Anti-Virus programs on Servers (I'm not the one who set it up), but nevertheless it helped a lot :)

So I can't really tell you something about the Bayes configuration...

How can I fix the SpamAssassin-Bug? Do I just have to change that file? (I didn't find it...)
