SMTP авторизация в exim, с использованием системных пользователей. Столкнулся с такой проблемой, что эта авторизация является как бы "не обязательной". Она вроде как бы и есть, но отправить можно и без нее...

вот пример конфига:

Мож кто сталкивался с этим?

• SMTP авторизация в exim,ALex_hha, 22:56 , 17-Мрт-09
• SMTP авторизация в exim,met3x, 14:22 , 18-Мрт-09

Думаю, для системных пользователей надо смотреть в сторону acl_not_smtp

Проблема решена, нада было к каждому accept'у в acl_check_rcpt добавить authenticated = *
