Firewall and Outgoing Email

I've recently added a 2nd email account to Outlook. This new account
is not from my ISP so the SMTP server requires authentication (same
username and password as the POP server). It worked OK for the first
few days and then suddenly I couldn't send any email (incoming email
was OK). My Windows XP firewall was enabled and someone suggested that
it might have something to do with the firewall and that I switch the
SMTP port from 25 to 587. I did that and everything has been fine
since then (for the past 3 days).

Was it really my XP firewall that caused the problem, and if so, is
there any way I can reconfigure my firewall to allow outgoing email to
pass through without having to switch the port? One disadvantage I
notice about switching the SMTP port is that Norton Antivirus no
longer scans the outgoing email.

Thanks.
