Question How are you dealing with spam

[Bogdan1]

Hi,

I'd like to ask, how are you dealing with spam like "viagra pills, sun glasses(fake ones), etc.." and spam that has image in body instead of text?

How yours spamassassin settings looks like?
Which blackholes are you using? Mine: zen.spamhaus.org;xbl.spamhaus.org;bl.spamcop.net;b.barracudacentral.org;abuse.rfc-ignorant.org;cbl.abuseat.org;nomail.rhsbl.sorbs.net but looks like it does nothing.

PS: Sometimes I'm getting spam in korean language(因为您与***.com的合作关系) and it has 0.2 spam score...

Thanks

You can filter foreign languages.

/etc/mail/spamassassin/local.cf

You'll want to add/modify an entry for "ok_languages" - You'll list the ISO language codes for the languages you do want to accept separated by spaces. Example;

en es ru

(english, spanish, russian)

I install a reverse proxy in front of Postfix (ASSP) and have been using that for almost 15 years.
That proxy (written in Perl) handles all the spam in realtime.
It sits in between the foreign MTA and the local MTA and manipulates the communication.

With an iptables nat rule I snatch the incoming port 25 traffic before it reaches postfix and feed it to the incoming port of ASSP.
ASSP is then giving it back (manipulated) to Postfix on port 25.
No configuration files need to be altered.
