Magento/exim emails not arriving, sent to and from own domain - magento

Question

We have an interesting problem related to Exim. We use Magento.
Emails are being sent by our server to customers and we have the send copy by separate or bcc in backend. We use Google apps MX.
But the email never arrives. If the email is sent to a different email address or domain then it arrives. And if it is the same account:
sent from: info#domain.com
to: customer#house.com
bcc: info#domain.com
the emails don't arrive # info#domain.com
Question: what can this be? I have the idea that exim is not sending the email with info#domain.com to the Google apps MX server for sending
ps. I already read this, but that is OK and not the problem http://inchoo.net/ecommerce/magento/fight-spam-emails/comment-page-1/#comment-53370
Major thanks

Answer 1

I changed the exim.conf file but this is not The solution. Email from and to The Same domain. And from and to The Same email ard not sent
As I understand it:
The code below looks at local_domains to see of the email is for here, or the outside world. As our email is not handled by the local mail server, but rather google local domains should also be routed via smtp
this line excludes local domains from smtp
domains = ! +local_domains
so we uncommented it
thx
# This router routes to remote hosts over SMTP using a DNS lookup. Any domain
# that resolves to an IP address on the loopback interface (127.0.0.0/8) is
# treated as if it had no DNS entry.
lookuphost:
driver = dnslookup
# domains = ! +local_domains
ignore_target_hosts = 127.0.0.0/8
condition = "${perl{check_limits}}"
transport = remote_smtp
no_more

Answer 2

I've run into this same problem and this is how I solved it. Instead of changing lookuphost like the other answer, I added another router
In the routers section of my exim conf after the lookuphost router, I added
routetogoogle:
driver = manualroute
route_list = mydomain.com
transport = remote_smtp
This manually forces anything going to mydomain.com to use the remote_smtp transport which will look up the correct MX records. Subtle difference from changing lookuphost - but this will allow you to still deliver mail locally for other domains if needed.

Answer 3

I have a magento running in an EC2 instance and for email hosting I am using bluehost, I solve this by setting "Set Return Path" to Yes in System->Configuration->Advanced->System->Mail Sending Settings
