postfix sender address rewriting
Hi, I have a postfix server that relays to an exchange server. All of my unix/linux systems send to this server, the problem is the form the mail is sent with, the sender address is Code:
username@hostname.domain.local I need to rewrite every sender address to unix@maildomain.com for this I added the following entry to main.cf: Code:
sender_canonical_maps = hash:/etc/postfix/canonical /etc/postfix/canonical: Code:
/domain.local/ unix@maildomain.com I ran the postmap command and restarted the mailserver but it's not working, any idea? -------------------------------------------------------------------- Edit: ok found the solution in main.cf Code:
sender_canonical_maps = regexp:/etc/postfix/canonical instead of hash, works now -------------------------------------------------------------------- Edit2: but just works for localhost, and not for relay hosts  ------------------------------------------------------------------- Edit3: needed to append the line Code:
local_header_rewrite_clients = static:all to main.cf hurray!!  ------------------------------------------------------------------ Edit4: hm now I need a solution, that writes the original hostname to the subject, because now I can't determine the sender host of course it can be added to the specific mail script, but we have about 300 mailscripts ------------------------------------------------------------------ Edit5: have the solution, regular expressions and header_checks, details tomorrow .. to main.cf: Code:
header_checks = regexp:/etc/postfix/header_checks to /etc/postfix/header_checks: Code:
/From:.* <.*@(.*)\.domain.local>/ REPLACE From: $1 <unix@maildomain.com> this will not write the hostname to the subject, it writes it to the from field, looks like Code:
From: hostname <unix@maildomain.com> outlook displays this name in the from column, which is absolutely perfect for my needs Last edited by funksen; 09-08-2009 at 05:17 AM.. |
