[Dovecot] dovecot-antispam and Thunderbird, Outlook, etc.

Hi,

In the documentation of dovecot-antispam it is mentioned that moving mails out of the spam folders trains them as non-spam. I.e. thunderbird automatically deletes old spam messages (after a time limit, i.e. 14 days). Will this also train the old spam messages as non-spam?

Cheers,

Eddy
