Question : problem connecting to SMTP

I have a WIN 2003 server.  I have a SMTP server on it and now I want to connect to that mailserver from home to send a mail.  I have allowed relaying from my home IP, etc. but I can't get it to work.

Incoming mail work fine (using the built-in POP3 service on the server) but when trying to send with Outlook express I get socket error 1051 error 0x800CCC0E

Leave "(All Unassigned)" in "IP address" field and enter alternative port (for example 2525) to "TCP port" field. Press "OK" three times.
