e-mail bouncing

I'm having a problem with e-mails bouncing back from a sister company of a
company that I have a SBS2000 system installed, other e-mails from other
domains including my own seem to be fine.

The e-mail domain on the SBS2000 is similar to @abc.co.uk and the sister
company who are not running an SBS is similar to @xabc.co.uk.

The sister company sends the e-mail via a POP account and after a couple of
days they get a message saying postmaster@abc.co.uk could not deliver the
e-mail.

I have checked the e-mail logs on the Server and can not find any e-mails
from the sister company.

E-mails from the SBS2000 to the sister company are also working OK.

Has any one seem anything similer and any idea's on how to resolve this
problem ?

Regards

If they are bothusing the same ISP, then it is possible that they have a DNS
issue. Use NSLOOKUP to check.
