This sounds strange. You cannot access the POP3 port of a POP3 client (email application), only that of a POP3 server (at your ISP). Clients can only connect to servers, not the other way around. Also, POP3 is not used to send mail, only to receive mail. For sending mail you use SMTP. If you are running a POP3/SMTP email application (client) inside of your firewall, and want to access a POP3 server (to fetch your email) or an SMTP server (to send email) outside of your firewall, then you may have to connect through a (SOCKS) proxy. See below. If it is the other way around (you are outside of the firewall with your POP3/SMTP client, and the POP3/SMTP server you are connecting to is inside of the firewall), then you are probably out of luck -- unless the sysadmin agrees to "punch a hole" in the firewall for you.

CERN proxies do not support POP3 or SMTP. They can only be used for HTTP and (usually) FTP and gopher. If you want to be able to access services other than these through a proxy then you need a SOCKS4 or SOCKS5 proxy. -- Holger Kruse [holger--rebol--com]
