I will try the suggestions so far.

I have no idea at the moment how to generate an email on this new server. In addition, it is not my email choice, but whichever one vBulletin is using. We have no intention of using this machine for serving mail.

Our domain is nawcc.org, however the vBulletin site is mb.nawcc.org. The mx record for nawcc.org points to an exchange server. All I want from the mail services on the whm/cpanel machine is to send out the mail generated by vBulletin and other applications. It would be nice to support the email integration mod, but we have another facility that performs a very similar mail reflector service, so I could do without that.

I have full root access to this machine, but I did not install the whm/cpanel. I did create the mb.nawcc.org domain on the machine and copied the vBulletin to it. I was a PDP-8/PDP-11/VAX developer for Digital Equipment years ago but I am very rusty with unix/linux. I spend a lot of time with --help.

There is currently no mx entry to mb.nawcc.org, only for nawcc.org.

The tail of exim_mai.nlog is shown below. There are lots of entries and several .gz files also, so it looks like vBulletin is trying to send out mails, but is not succeeding because the network does not believe it is authorized.

I would guess this is related to the missing mx record.

This was working just fine on our dedicated server at WestHost where they set up the server for us. We are mostly on our own with the colocation server.
