Hi all, I am facing a very peculiar problem, I'll try to explain the setup first, I have 2 servers at my place 1) Server A --- Mail server ------ Running Sendmail. 2) Server B --- Proxy server ------ Running Squid. Both the servers have a real (live) IP and a Local IP for internal network purposes. Whenever I try to contact the 110 port i.e. POP server of my mail server from my internal network it gives trouble, sometimes it would connect and most of the time's it won't. But if I contact it through the real IP of the machine from either within my network or from any other location it works just fine. Please if anybody could suggest me the cure to this problem asap.
