RE: can the telnet command be automated?

[<tim.dclinc@xxxxxxxxx>]

I found a technique to validate an email address using telnet port 25 as
follows:

telnet smtpserver:25

then type the following 

helo <yourdomain.com>
mail from: <info@xxxxxxxxxxxxxx>
rcpt to: <jimbsa2aa4@smtpserver>


If there is a better way of doing this, im up for it. 

Here are two sites for reference

I thought you were trying to automate a telnet connection?  If so, why 
are you connecting to an SMTP (e-mail) port?!
