Does the smtp server forward mail via port 25?

If I activate my Linux server's smtp server, and point my email clients 
to it, the email clients will use port 25.

When my smtp server goes to deliver the email to the recipient's 
domain's email server, what port does it use? Does it talk to an smtp 
server, or the pop3 server?
