SMTP & OWA running successfully. Created In/outbound POP3 protocol and ip packet filtering rules created server publishing rule pointing 110 from external nic ip to the E2k server ip. I have also run the secure mail wizard after I manually created the rules and didn't appear to do anything. I just can't telnet 110 to the ISA external ip (to hopefully be routed to the internal nic to then be forwarded to the E2k server) Naturally pop3 from external (internet) clients fail also. I have seen that there have been reports of POP3 not working with no explanation. Reinstall resolves this?????
