[cobalt-users] Mail settings

[Andy Jacobs <andy@xxxxxxxxxxxxxxx>]

I have a customer who has their own server running some package that handles
mail for them.  I think it's mailgate.  I've set the Raq up as follows:

mail.zeitner.com            xxx.xxx.xxx.xxx

Where the xxx are the ip address of the server in their office.

For some reason, if they send e-mail to another domain on my raq (me for
example), they get the message bounced back with 'No such user here'.

Now this has only started since we changed the DNS and they installed their
server.  I'm not convinced that mail is actually leaving their server.  I
think it's a setup problem at their end but I don't understand why it only
affects them sending mail to other domains on my server.

If someone could offer some suggestions I can go back to them with I'd be
grateful.

Cheers

Andy
