FreeBSD 5.3 и 6.0
Postfix 2.4.5
MySQL 5.0
Базы юзеров, алиесов, доменов лежат в мюскле.
Скопировал конфиги постфикса и SQL базы его с одной машины на другую. (всё один в один)
на новой машине почта юзерам приходит и уходит хорошо, а вот на алиесы не идёт.
Постфикс её забирает, но потом возвращает письмо "Undelivered Mail Returned to Sender" <staff@rosserv.ru>: unknown user: "staff@rosserv.ru"

Где ещё посмотреть?
