If you can telnet to port 25 on the ISP, you could then use netcat to send
a file with the smtp chat. It's pretty easy to set up. Here's an
[chip at trailerbarn ~]$ telnet localhost 25
Connected to localhost.
Escape character is '^]'.
220 trailerbarn.pupman.com ESMTP Postfix
MAIL FROM: joey at pupman.com
250 2.1.0 Ok
RCPT TO: chip at pupman.com
250 2.1.5 Ok
354 End data with <CR><LF>.<CR><LF>
Subject: Hi there
This is a test message
This will actuall provide a subject line as well. You can put other
headers in too.
