Hi, The background:
Long-time Gentoo user, newbie to mail server setup. I've got a Gentoo server (~amd64) and I set up Postfix and Dovecot following this guide: http://en.gentoo-wiki.com/wiki/Mail_server_using_Postfix_and_Dovecot I'm using postfix-2.8.4 and dovecot-2.0.13 So far, everything works as advertised. I've added a domain, created accounts, additionally I've set up sqlgrey, DKIM signing and SPF, sender-ID and all of that good stuff. My sent mail goes out successfully and incoming mail gets delivered to the virtual mailboxes and everything's working properly as far as I can tell. The problem: My existing (hosted) mail server has a catch-all account so any mail to the domains I own goes to me. I believe they use qmail. The delivered-to header on the messages retain the address of the original message, not the catch-all address to which it is forwarded. Why do I care? I basically use a different address for every site or person I interact with and then sort them out into folders based on the delivered-to address. (For example if I bought something from Sears I would use se...@example.com as my email address). With postfix, it doesn't work that way. I set up a catchall, but the delivered-to: header becomes catch...@example.com for all of the catchall mail. I can't change my rules to use use the To: address because it is not reliable (BCC, spam...). The idea: Assuming I can't do anything about how Postfix handles the Delivered-To header, I'd like to insert a new header entry (X-Originally-To: or something like that) into incoming mail before it hits the catchall forward, so I can know to whom the email was originally addressed... but i don't really know where to begin. The question: Are there any postfix gurus out there who can point me in the right direction? Thanks in advance for any tips or advice (or if you want to tell me that I'm doing it all wrong). Thanks, Paul
