let me start off with the specs - win server 2003 std, exchange 2003, behind cisco pix 501
client: using outlook 2003 -pop3 / smtp
client's trying to use Pop3 for emails -- he can receive email, but can't send email out from the smtp, all the credentials are all correct...
see snap shot -
i can telnet to the mail server through port 25 and 110 without any problems
port 110 and port 25 are opened on the cisco firewall and is routed to the exchange server..
are there some kind of setting i must change on my smtp protocol?
it just happened all of a sudden --
someone please help......been working on this for hours without any success....
thank you in advance....
