Virtualmin open source latest stable here, on a Debian10 with dovecot and spamassassin (spamd).
Hoping it’s the right system page, here are my server’s spamassassin options: https://imgur.com/a/WWtZFUZ
I’m seeing (and hearing rants about) a fair number of those “canadian pharmacy” typical kind of emails successfully passing through, and looking at their source, I see they have a score of 3 or 4, max.
Those emails are read through IMAP, on thunderbird (2 email accounts, 2 websites).
I wouldn’t mind training spamassassin, after all, that’s what bayesian algos are for. However, I’m afraid I simply don’t find where one may do such a thing, pardon me to ask, but would someone know if there is an official, guaranteed to work method?
I’ve starting hitting the Spam categorization button in thunderbird, however I would tend to doubt this will magically do the job.
Better, I saw instructions here: https://www.math.ias.edu/computing/faq/train-SpamAssassin
, however they are not virtualmin-specific, and I have zero way of knowing if they would work in a virtualmin context. It says “create a Spam folder, and move the spam emails inside”.
Would it also work with imap?
Does virtualmin cron spam learning, or must it be triggered by hand, as I’ve seen for other systems with web searches?
Should the Spam folder be created by hand in a terminal or by SFTP, or may it be created within usermin?
You see the idea for my questions, in a virtualmin context, I do not know if it would work, and how it would…
Thanks if someone knows and can tell
