Problems connecting to port 25

[JJB]

Your ISP has closed ports 25 and 80 for all their non-commercial
accounts.
This is very normal, and becoming standard among ISP's.

Subject: Problems connecting to port 25

Hello all,
     I just joined this list, I didn't see to much help from the
FreeBSD_Questions side so I thought I would ask here.  I currently
have 2 FreeBSD 5.1 boxes.  one is a test server the other I would
consider production.  Both provide Email/Web/DNS services.  I have a
firewall I found on the internet, and everything works,
DNS/Web/Webmin/SSH but I cannot telnet into port 25.  Can someone
tell me what I am doing wrong?  Or send me a copy of a Firewall that
will improve my current one?  I found alot of samples on the net,
but
nothing seems to work.  I am running Qmail / MailDrop.  Not sure if
that helps.

Thanks in advance..
