Hello. I have postfix running on linux box. I setup OpenDKIM with both smtpd and non_smtp milters. I also set my address in DNS as permitted IP for SPF.
So far, so good. But I want all my mail to be forwarded to gmail. Some user sends me email from user@some_sender_domain. If I use .forward or alias, then postfix doesn't change "From" header, so gmail believes email was sent from @some_sender_domain. This domain doesn't have my box IP as permitted in DNS, so SPF failed. I can change header using headers_check. But then DKIM signature would be broken because some_sender_domain signed email and I changed it. It seems that I need to: * Change headers * Sign email with my DKIM * Forward it to gmail But milters are not applied on forwarded emails because they aren't locally generated (or I failed to configure it correctly?) I can fix it using custom script that reads my local email and sends it to gmail. But how can I do that with postfix? Ilya.
