[BlueOnyx:01199] e-mail alias problem

[Stuart Clark (Datacenta)]

Hi 

I recently reported that I was having problems with the aliases
resolving on certain sites. I have got to the bottom of the issue and
thought I would update the list.

We have external DNS servers so this is not setup on the blueonyx
server.
If you create DNS for the site using CNames then any aliases will not
resolve.
If you create DNS using ARecords the aliases resolve just fine.

It seems that sendmail cannot resolve cnames.

Regards,

Stuart
