I've spent hours on websites, checked config files etc. But can't find the problem. Debian server, with Spamassassin and Postfix. Spamassassin is enabled (checked it on command line). In the mail.log, some lines are relay=spamassassin, and it is writing logs when restarting service.

Here are my Postfix and Spamassassin config files. Please can you check if all is OK and give me a way to find the problem?

Postfix (main.cf):

# of the file, see the master(5) manual page (command: "man 5 master" or
# on-line: http://www.postfix.org/master.5.html).

# Do not forget to execute "postfix reload" after editing this file.

  • Does it modify the subject to "*****SPAM*****" or does it do nothing at all?
