Multiple Domains with Exim 4.34


Hello all....

I've looked around the forums and read what's there, and I'v also read the Exim FAQ, but I'm still having problems.

I think what I want to do is pretty routine, but I don't know enough about email to make it happen.

My linux box's domain is theheatsinkbbs.ca. I have all servers (web, ftp, email, etc) running just fine on that domain. Now I want to move another of my domains over (jonwatson.ca).

The webserver part is fine, it's running, but I can't seem to wrap my head around how to get my box to accept and deliver traffic for the jonwatson.ca domain.

I have multiple jonwatson.ca email addresses, in fact too many to handle, so I think what I want to do is have all jonwatson.ca email put into a specific email box.

This is the snippet of the Exim doc I am working with:

Code:
Q0402:  How do I arrange for all incoming email for *@some.domain to go into one pop3 mail account? The customer doesn't want to add a list of specific local parts to the system.

A0402:  Set up a special transport that writes to the mailbox like this: 

   special_transport:
     driver = appendfile
     file = /pop/mailbox
     envelope_to_add
     return_path_add
     delivery_date_add
     user = exim

The file will be written as the user exim. Then arrange to route all mail for that domain to that transport, with a router like this:

   special_router:
     driver = accept
     domains = some.domain
     transport = special_transport
I understand that I have to modify /pop/mailbox to read /var/mail/<username> and that some.domain should be changed to jonwatson.ca.

My question is ..where do I put this stuff? I'm using exim 4.34 and therefore have an /etc/exim4 directory. In that directory there are directories for router and transport which are filled with individual files. I assumed from this that I was to create new files in these directories and plunk the apppropriate code in there, but that doesn't work.

When I send an email to a jonwatson.ca address, it get's bounced with the following error:

Code:
This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) 
failed:

   me@jonwatson.ca
     Too many "Received" headers - suspected mail loop

------ This is a copy of the message, including all the headers. ------

Return-path: <heatsink@theheatsinkbbs.ca>
Received: from theheatsinkbbs ([192.168.1.1])
	by theheatsinkbbs with esmtp (Exim 4.34)
	id 1CBvU9-0001h4-Sc
	for me@jonwatson.ca; Mon, 27 Sep 2004 07:24:09 -0600
Received: from theheatsinkbbs ([192.168.1.1])

	for me@jonwatson.ca; Mon, 27 Sep 2004 07:23:38 -0600
The 'Received' header gets repeated about 50 times....

Any ideas?

Thanks!

Jon

hi try this
(i think this domainlist can still contain your actual machine domain as well)
Code:
domainlist local_domains = @ : \
    @[] : \
    localhost : \
    partial-lsearch;/etc/exim4/virtual.domains
then under directors configuration after the real_local: section is over make a new virtual: section
Code:
virtual:
  driver = redirect
  allow_defer
  allow_fail
  data = ${lookup{$local_part@$domain}lsearch*@{/etc/exim4/virtual.users}}
  domains = partial-lsearch;/etc/exim4/virtual.domains
  retry_use_local_part
then just make some files that look like this
Code:
--- virtual.domains ---
  example.com
  example.net
---

--- virtual.users ---
  #example.com
  regularuser@example.com     : localuser
  forwardinguser@example.com  : someuser@example.org
  *@example.com               : catchalluser

  #example.net
  regularuser@example.net     : localuser2
  forwardinguser@example.net  : someuser2@example.org
  *@example.net               : catchall2
---

Hi

Thanks for the response. I tried your suggestion and the routing seems to fail....here's what I get when I run an exim -d -bt me@jonwatson.ca

I'm not savvy enough to intrepret all of this, but it appears that the 'failed to expand...' line probably contains a clue...I just don't know how to read it properly.

I have the following virtual.domains and virtual.users files as well:

Code:
#virtual domains
theheatsinkbbs.ca
jonwatson.ca
Code:
#theheatsinkbbs.ca
heatsink@theheatsinkbbs.ca : heatsink
*@theheatsinkbbs.ca : heatsink

#jonwatson.ca
me@jonwatson.ca : heatsink
*@jonwatson.ca : heatsink
Thoughts?

Thanks!

Jon

PS - should mention also that the messages are definitely arriving at the box. Here's a snippet of my mailq

Code:
theheatsinkbbs:/etc/exim4# mailq

52m  1.1K 1CBywA-0001zA-4G <xxx@xxx.com>
          me@jonwatson.ca

37m  1.1K 1CBzAr-00021g-3v <xxx@xxx.com>
          heatsink@theheatsinkbbs.ca

36m  1.1K 1CBzB3-00021h-R0 <xxx@xxx.com>
          me@jonwatson.ca

theheatsinkbbs:/etc/exim4#
I put the 'xxx''s in to save my work email address from publication
