ЗДравствуйте

Используется Postfix + Cyrus. Недавно настроил Spamassassin и в логи начались сыпаться ошибки:

-----------
Aug 31 07:58:03 mail postfix/smtpd[28249]: warning: non-SMTP command from localhost[127.0.0.1]: Return-Path: <user@example.com>
Aug 31 08:14:36 mail postfix/smtpd[28325]: warning: non-SMTP command from localhost[127.0.0.1]: Return-Path: <user@example.com>
--------------

Настроена пересылка всей исходящей почты на ящик bcc@example.com. После появления этих ошибок письма в этот ящик перестали попадать.

Догадываюсь, что это где-то в правилах smtpd, но почитав гугл, попробовав несколько вариантов, так и не нашёл верного.
