Saw a related article in the lists and wanted to contribute. I could telnet to localhost 110 but when using the nic's IP it would barf: Nov 27 20:54:00 mx1 popper[2565]: Unable to obtain socket and address of client: Socket operation on non-socket (88)
RH during install, asks for a firewall setting, I took 'customize' It builds an IPTables script that denies 110 & 995 so go to /etc/sysconfig/iptables and modify theirs "RH-Lokkit" or write your own ruleset. This will kill the problem, I saw on the list as an Outlook Express error, where it says something like 'server terminated the connection, possible causes, blah, blah' Regards -Austin
