I do know that SpamSieve author Michael Tsai does support his product but
doesn’t support MailMate. Also his support for Mail is outstanding.
Personally, I use a separate “drone” SpamSieve set up for filtering my 9
accounts outside of MailMate. It works fine. Of those accounts none are
Xfinity
I have an account set up in MailMate pointing to the Xfinity IMAP server, and I
use SpamSieve as a spam filter. Messages that get marked as spam are meant to
be sent to the Junk folder.
What I see, however, is the spam messages appear in the INBOX folder with
little trash can icons in the leftm
