[Dovecot] Using IMAP keywords instead of mailboxes for spam with dovecot-antispam

Hi,

Some email clients, like Evolution, use IMAP keywords to flag spam instead of moving mail to dedicated spam mailbox. This is very useful, as false positives can be easily "moved" to original mailbox simply by removing $Junk keyword.

I couldn't find a way how to integrate antispam software, like dspam, with dovecot, so that antispam automatically learns ham/spam.

I have found Johannes's dovecot-antispam plugin. Unfortunatelly, it doesn't have IMAP keywords support, autolearn is based on folders.

Is there any solution for this use case?

Thanks,

Jan
