Hello everyone, I don't know if this is the right area to post this or not but here we go.

I have a user that is having e-mail issues. She isn't receiving e-mail from two other users. User1's e-mail is returned with a smtp 550 error of host unknown (our domain name). User2's e-mail isn't being returned with an error message, but it isn't getting delivered either. I checked through everything I can think of and found nothing unusal. This is an internal mail delivery issue inside the same post office and domain. We are using SUSE linux for the GW8 mail server. Any suggestions???
