Hallo,

In the last weeks I receive more SPAM mails about sexual enhancers and bitcoins. Is it possible to configure or train the spam filter so that users are no longer annoyed by these mails?

Many thanks in advance!

Re: Training the spam filter

You can collect the spams, then run "sa-learn" command as Amavisd daemon user to learn spam.

Re: Training the spam filter

How do I collect spam? Do I have to move it to the spam folder?

And then I have to do this?:

sudo -u amavis sa-learn

You can use Roundcube plugin "markasjunk" to collect spam. When user moves one email to "Junk" folder, the email will be considered as spam, you can configure 'markasjunk' to run 'sa-learn' when mail was moved to Junk.

I want to clarify process of training the spam filter. I found following articles
Store SpamAssassin bayes in SQL
Auto learn spam/ham with Dovecot imap_sieve plugin

My questions are:
1. Does the installer (*.tar.gz) configure autolearn functionality ?
2.If not what step should I do to configure it ? Is it enough to do this Store SpamAssassin bayes in SQL and then Auto learn spam/ham with Dovecot imap_sieve plugin ?


I also checked sa-learn

 su -s /bin/bash amavis -c "sa-learn --dump magic" 
 
0.000          0          3          0  non-token data: bayes db version
0.000          0          0          0  non-token data: nspam
0.000          0       2416          0  non-token data: nham
0.000          0     132223          0  non-token data: ntokens
0.000          0 1606038707          0  non-token data: oldest atime
0.000          0 1606902065          0  non-token data: newest atime
0.000          0          0          0  non-token data: last journal sync atime
0.000          0 1606872248          0  non-token data: last expiry atime
0.000          0          0          0  non-token data: last expire atime delta
0.000          0          0          0  non-token data: last expire reduction count

What does value in columns means ?

Thanks in advance,
Roman

Not in the downloadable iRedMail installer, but it's implemented in the iRedMail Easy platform (https://www.iredmail.org/easy.html )

Latter one is required, but first one is optional but highly recommended for better performance.
