Official ask RedCream Questions Thread No.2

Are you excited for the 2nd installment of the hippest thread on /lounge/?

As the resident BATCH expert 'Cream I ask you this:
So I came across this http://www.webdigi.co.uk/blog/2009/how-to-check-if-an-email-address-exists-without-sending-an-email/

And I thought it'd be great to find a way to automate this. So I had a go myself in BATCH. It works alright til I get to the TELNET commands:


Code:
:start

cls
set /p email="Email to verify?"

cls

echo Checking
echo %text%

PAUSE

telnet mail.reddit.com 25
HELO HI
MAIL FROM: <youremail@gmail.com>
RCPT TO: <%email%>

I know the last line is probably a syntax error anyway, but is there a way to do multiple telnet commands like this in BATCH? Right now it doesn't get past telnet mail.reddit.com 25

I know this is piss-easy to do in python or php, but I still want to know how to do it.
