Mail lists, gmail servers in mx and local users issue

Our mail is hosted at gmail.

Our mail server sends our mailing lists using Exim.

Our domain is example.com

If joe [at] example is on one of the mailing lists he does not receive
the mail as it is trying to deliver the mail locally rather than
sending to the gmail mailserver listed in the mx.

How can I fix this?

Thanks!
Cameron

You could add a router towards the top of your list of
routers that looks something like:
---
smarthost:
driver = manualroute
route_list = example.com aspmx.l.google.com:alt1.aspmx.l.google.com:alt2.aspmx.l.google.com:aspmx2.googlemail.com:aspmx3.googlemail.com
transport = remote_smtp
---

That should work I think assuming you want everything destined
for example.com on this mail server to route through your Google
Apps accounts. This particular router should probably be at the
top of your list of routers since they are processed in order.

I doubt it, but anyway...

Assuming you want no addresses at your domain to be treated as local
by your Exim MTA, take your domain name out of the 'local_domains'
domain list (assuming a stock config).

Cameron,

.. all of which also raises the question:

How, and to what address(es) do 'posts' TO the list arrive?

They probably need a bit of recognition and handling logic as well, lest they be
refused by the settings so far suggested.

JFWIW - life is considerably simpler (especially when 'bounces' are returned) if
the MTA/MLM can be given a valid <domain>.<tld> of its own, and outbound headers
set to what makes sense w/r distinguishing 'From:, 'Reply To:', posts,
moderation, subscribe/unsubscribe, and the return path needed by the inevitable
bounces a list will encounter as members change addresses, overfill quotas, or
go on vacation.

All old stuff, and probably better covered in your Mailing List Manager software
docs and their support/user list archives than here.

As a minor tweak, we use the following config to simulate the
priorities of the suggested Google Apps MX records:

hosts_randomize = true
route_list = example.com
aspmx.l.google.com:+:alt1.aspmx.l.google.com:alt2.aspmx.l.google.com:+:aspmx2.googlemail.com:aspmx3.googlemail.com:aspmx4.googlmail.com:aspmx5.googlemail.com
