Exim4 Smart Host Relay
- by ColinM
I am running Exim 4.71. I want to:
Route all email from A.com through mail.A.com
Route all email from [B-E].com through mail.B.com
Send all other email directly.
Here is the configuration I have that doesn't work like I hoped:
domainlist a_domains = a.com
domainlist b_domains = b.com : c.com : d.com : e.com
begin routers
smart_route_a:
driver = manualroute
domains = +a_domains
transport = remote_smtp
route_list = +a_domains mail.a.com
no_more
smart_route_b:
driver = manualroute
domains = +b_domains
transport = remote_smtp
route_list = +b_domains mail.mollenhour.com
no_more
dnslookup:
driver = dnslookup
domains = ! +local_domains
transport = remote_smtp
ignore_target_hosts = 0.0.0.0 : 127.0.0.0/8
no_more
When I send an email e.g. with PHP's mail() or Zend_Mail_Transport_Smtp setting both From: and Return-Path: as [email protected], the smart_route_a router is not used, the dnslookup is used instead. Disabling dnslookup results in no mail being sent.
From the logs it appears that email sent to [email protected] uses smart_route_a, but the same email sent from [email protected] to [email protected] is sent using dnslookup.
How do I make email from [email protected] be relayed via mail.a.com?
