I did some research and found out that my ISP's SMTP server is 
smtp.comcast.net.

If I configure my mail functions to connect to this should my script be able 
to send e-mails?

Research and Experimentation (yes, I did some!):

I tried connecting to it using this telnet command:

telnet smtp.comcast.net

But I got this: 

Connecting to smtp.comcast.net..could not connect to smtp.comcast.net on port 
23. A connecting attempt failed because the connection party did not properly 
respond after a period of time..

Then I tried this:

telnet smtp.comcast.net 25

A new window popped up and said this:

220 Comcast.net - Mailennium ESMTP/Multibox rwcrmhc11 #140

Did it work? So if I put smtp.comcast.net in php.ini should my e-mail script 
work?
