postfix – mail forward se zachovanim lokalni kopie

K tomuto ucelu jde pouzit budto mail alias
virtual_alias_maps = mysql:/etc/postfix/mysql-virtual-alias-maps.cf
nebo bcc_maps
recipient_bcc_maps = mysql:/etc/postfix/mysql-recipient-bcc-maps.cf

U me vypada query takto:
query = SELECT forward FROM users WHERE CONCAT(username,’@’,domain) = ‘%s’ and forward != ”
V tabulce s forwardem mam puvodni mail a vsechny, na ktere chci forwardovat.

Dlouho jsem nemohl prijit nato, proc mi ale mail chodi do forwardnute schranky 2x. Bylo potreba pridat do
/etc/postfix/main.cf
-o receive_override_options=no_address_mappings
smtp inet n – – – – smtpd
-o content_filter=spamassassin
-o receive_override_options=no_address_mappings

ale pozor, nedat to do radku se submission:
submission inet n – – – – smtpd

K duplicitnimu mailu dochazi proto, ze postfix zpracovava stejnou zpravu dvakrat v pripade toho content_filtru s antispamem. Proto se tam musi pridat ten radek s no_address_mappings
