I've read many examples about using a shell script to test a mail server
(sendmail, postfix, etc) such as:
#!/bin/bash
telnet 1.2.3.4 25 << _EOF_
HELO abc.com
<- smtp conversation here (mail from, rcpt to, data, etc)
_EOF_
When I execute it, I get:
220 xyz.com ESMTP Sendmail 8.11.6/8.11.6; Fri, 11 Oct 2002
19:59:20 -0400
Connection closed by foreign host.
I've tried many ways to do it but it doesn't work. I've read somewhere that
"telnet is not interactive so it will not work". I know Perl is much better
and gives more control, but I want to do it first en bash script just for
fun :) Any suggestion?

Freddy Chavez.
