I run spamassassin and postfix on my mailserver, but don't run amavisd.

Thanks for your response. If I can't get SpamAssassin working with amavisd I'll do that. But I assume someone must have it working since it is referred to in the CentOS wiki.centos.org in various Howto's.

spamassassin adds a header to incoming email that looks something like this:

X-Spam-Status: No, score=-103.5 required=5.0 tests=AWL,BAYES_00,HTML_MESSAGE, RCVD_IN_DNSWL_MED,RP_MATCHES_RCVD,USER_IN_WHITELIST autolearn=ham version=3.3.1

Yes, I realise that, and SpamAssassin on my system works fine if run with sample email spamassassin -D < spammail > spammail.out But as far as I can see, amavisd is not starting spamd running.

You can then configure your mail client to trash or sort email based on the presence or absence of the [SPAM] tag in the subject line.

Unfortunately, as I said, SA does not appear to be processing any email. Amavisd is setup to send any spam to ~/quarantine/ but sadly this directory remains empty.

I just checked on my server - no process for spam* but there are 3 for amavis and I get emails into my client with the "***SPAM*** " heading, thus spamassassin is running and doing the task, called and managed by amavisd. I have never done an autopsy on the whole mix as it just worked when I followed the recipe.

Thanks for your response. I too have 3 amavis processes running: one (master) and two (virgin child).

Which recipe did you follow? Please could I see either your amavisd.conf or the diff file between your current version and the original one?

I'm wondering if email is being passed from postfix to amavisd on my system.

I should say that I do not understand from this document what is meant to happen to spam. I understand that a Spam header is added, but what actually happens to email considered to be spam?

Thanks for your response.

Just to add to my remark above, I realize now that I should have made the change -------------------------- # $QUARANTINEDIR = undef; # -Q $QUARANTINEDIR = "$MYHOME/quarantine"; # -Q -------------------------- in /etc/amavisd/amavisd.conf , after which spam should go to this directory. However, this change did not affect the fact that email does not appear to be being processed by SpamAssassin.

IIRC, SpamAssassin is run from Amavisd-new so the regular SA daemon does not run on its own.

I realize that, but I don't see any entry in amavisd.conf that will start spamd running. The only relevant entries in amavisd.conf as far as I can see are ------------------------------------ [tim@alfred amavisd]$ grep $sa amavisd.conf $sa_tag_level_deflt = 2.0; # add spam info headers if at, or above that level $sa_tag2_level_deflt = 6.2; # add 'spam detected' headers at that level $sa_kill_level_deflt = 6.9; # triggers spam evasive actions (e.g. blocks mail) $sa_dsn_cutoff_level = 10; # spam level beyond which a DSN is not sent $sa_crediblefrom_dsn_cutoff_level = 18; # likewise, but for a likely valid From # $sa_quarantine_cutoff_level = 25; # spam level beyond which quarantine is off $penpals_threshold_high = $sa_kill_level_deflt; # don't waste time on hi spam $sa_mail_body_size_limit = 400*1024; # don't waste time on SA if mail is larger $sa_local_tests_only = 0; # only tests which do not require internet access? $sa_spam_subject_tag = '***Spam*** '; ------------------------------------ These seem to be the only lines in this file involving SpamAssassin.

However, stopping SpamAssassin and then re-starting amavisd does not re-start SpamAssassin: ----------------------------------- [tim@alfred amavisd]$ sudo service spamassassin stop Stopping spamd: [ OK ] [tim@alfred amavisd]$ ps aux | grep spamd tim 4706 0.0 0.0 103244 840 pts/2 S+ 11:43 0:00 grep spamd [tim@alfred amavisd]$ sudo service amavisd restart Shutting down amavisd: Daemon [4651] terminated by SIGTERM [ OK ] amavisd stopped Starting amavisd: [ OK ]

[tim@alfred amavisd]$ ps aux | grep spamd tim 4734 0.0 0.0 103244 840 pts/2 S+ 11:43 0:00 grep spamd [tim@alfred amavisd]$ -----------------------------------
