This implies that you're trying to send mail either directly from your
machine to the world or are using a non-ISP provided mail service.
If it's the former stop it. :)
You really don't want to do direct to port 25 unless you're a proper mail
server. If you're doing this on your home internet connection, you don't
If it's the latter, I recommend doing this for many reasons. Any mail
service provider worth using will listen on TCP/587 and require TLS+auth
for outbound relay through this port.
(I used to feel quite indignant about this myself. A few years of dealing
with the type of crap that originates from ISP networks running a mail
service that people cared about changed this view.)
