Hosting external mail server troubles

[docjohn]

I have a domain in WHM/cpanel that has externally hosted mail servers and an externally hosted DNS. It uses web forms to send email to the organization.

Unfortunately, the email never leaves the local server.

I followed all the previous advice to remove the domain from /etc/localdomains and added it to /etc/remotedomains.

I also completely removed the DNS Zone for this domain via WHM. Restarted exim.

dig domain.com MX shows everything properly pointing to the right places.

Resolvers are set to ISPs nameservers.

However, when I send any email from this webform, it's still not getting to the remote mail server. The local server continues to collect it in the local mailbox. (Web serving on the box works fine.)

I'm at my wit's end with this one so any help would be appreciated, thanks!!

If you have root access see what the logs say. There's a few possiblities, but the logs are a good place to start.

Ok, so from exim_mainlog I see something like this:

2004-11-19 11:14:49 1CVCLR-00085j-7L <= abc@server1.domain.com U=abc P=local S=1512
2004-11-19 11:14:49 1CVCLR-00085l-7w <= abc@server1.domain.com U=abc P=local S=964
2004-11-19 11:14:49 1CVCLR-00085l-7w => abc <abc@domain.com> R=localuser T=local_delivery
2004-11-19 11:14:49 1CVCLR-00085l-7w Completed

It clearly thinks user "abc" is a local user that needs to be delivered locally to server1.domain.com. My problem seems to be with exim?

I don't usually have to setup an external mail server like this, that's why I'm having so much trouble....
