Hi there!

We have a mail server here behind the firewall that we do not want outside 
access to and we have given it a sub domain name which has not yet been 
activated anyway. Some users should only be allowed to mail internally but 
other users, such as supervisors and managers (with a different subdomain that 
DOES exist) who use Fetchmail to retrieve mail from other servers need to mail 
both internally and externally.

Is there a way to block a specific sub domain name from mailing externally 
either on the computer itself or on the firewall without fully blocking all 
mail from going outside?

Thanks!

Best Regards,

Ken Gilmour
