Ситуация. Есть внутренний домен svgc.net и внешний svgc.ru. В домене svgc.net стоит Exchange, который всю почту наружу шлет через шлюз Postfix. Хочется, чтобы почта от юзеров svgc.net наружу уходила как от пользователей svgc.ru, для чего воспользовался возможностями sender_canonical_maps. Но вот что получается:

Return-Path: <shrdluex@svgc.ru>

Это поле Postfix поменял как мне и надо...

Насколько я понимаю, sender_canonical_maps должна бы и поле From поменять, ан нет. Или я неправ? В таком случае, как его можно изменить на Postfix?
