would it be possible to introduce, associated with the black list, a "bounce back" feature ?
edit: on a side note, I haven't experienced with the black list yet, can't tell if it just marks as spam, or blocks completely from downloading. The second option, really blocking, would be expected, but that's an issue in IMAP (I've been there already with Spamihilator, a really nice anti-spam, but when you're on IMAP, it just drives you nuts, because you keep synchronizing with the server, which in turn is normal >>> vicious circle >>> conclusion: full featured external anti-spam isn't appropriate on IMAP, unless it is at least aware of what folder is the spam folder on the server...OK
)
