This will take care of delivering the mail from the corp server to the user mailboxen on the regional office postfix server, and assumes MX corp.example.com remote office regional.example.com The following will go into the postfix config on corp.example.com, and enables the forwarding of mail to the remote regional office: /etc/postfix/main.cf recipient_canonical_maps = hash:/etc/postfix/recipient_canonical /etc/postfix/recipient_canonical j...@example.com j...@regional.example.com b...@example.com b...@regional.example.com j...@example.com j...@regional.example.com ^^You will need one entry per regional office user. To properly relay mail from regional.example.com through corp.example.com, so that all 'from' addresses are of form u...@example.com, on regional.example.com do /etc/postfix/main.cf relayhost = [corp.example.com] on corp.example.com do /etc/postfix/main.cf mynetworks = ip_addr_of_regional.example.com #this is additional local_header_rewrite_clients = static:all masquerade_domains = example.com That should cover it. -- Stan
