I have NSBS 6.5 installed on a server with BorderManager 3.8 [with mail
proxy configured] and Groupwise 6.5 configured. Everything looks alrite
but I cant receive mails while I could send.
I recall I had an experience where Bordermanager and DNS/DHCP was running
on the same server, the DNS proxy of BM was configured and that troubled
the DNS server greatly, i eventually got a solution from the forum that I
dont need DNS proxy if BM and DNS are on the same server.
Now, with this problem with the mail server, am i supposed to have mail
proxy and mail system on the same server?
What exactly is the job of a mail proxy?

Thank you.
