Вобщем хочеся следущее:
1. SpamAssassin определил писмо как спам. Exim положил это письмо в /home/spam/Maildir/new и выслал в ответ отправителю "Это письмо не доставленно потаму-что оно является спамом. Если вы хотите чтобы мы вас вычеркнули из чёрного списка пришлите письмо на postmaster@mycomp.ru ".
2. Все письма которые приходят на postmaster@mycomp.ru и еще пару адресов, не должны проверяться SpamAssassin -ом.

Что для этого нужно сделать ?
