So I am still running Mac OS El Capitan Server Edition on my Mac Mini. Recently, the Spam that comes through, has increased again and I wondered if there is any mechanism to implement AntiSpam in Mac OS X.
The Apple Knowledge Base only gives this article:
https://support.apple.com/kb/PH22351?locale=en_US
which is not exactly what I wanted.
Looking further, I came across these links, which proved helpful at the end:
According to that site the software will do this:
- spamtrainer assists Mac OS X Server mail services administrators in updating and maintaining their SpamAssassin bayes database.
- spamtrainer will read the designated HAM and SPAM mailboxes, update the SpamAssassin databases and delete mail that has been learned from.
After downloading the spamtrainer installation script and installing it I did the following:
Check the proper setup of junkmail / nojunkmail
sudo serveradmin settings mail:imap | grep junk
Result:
mail:imap:junk_mail_userid = "junkmail" mail:imap:not_junk_mail_userid = "notjunkmail"
When running spamtrainer now right away, it complains:
Either there is no mailbox called No GUID found for user: junkmail in the mailpartition or it has never been fed with mail. Either there is no mailbox called No GUID found for user: notjunkmail in the mailpartition or it has never been fed with mail.
So I go an create those users. Starting the Server.app plus adding the needed network accounts „junkmail“ and „notjunkmail“. Further I edit access so that these accounts only have access to the Mail service. Now I add these accounts to Mail so that I have access to them.
Now, finally, when I run
/usr/local/sbin/spamtrainer
it does what it should.
Using the install option I can also have it run as plist item.

That is all for installation, now let me see if it does what it should!
