1 Select 'START'-'RUN' and type 'CMD'


2 Type 'TELNET' [ENTER] then 'SET LOCAL_ECHO' [ENTER] (this will enable
text in the telnet session to be visible, by default it is not)


3 Type 'OPEN 25' [ENTER] (opens a connection to the SMTP



4 Type 'EHLO' [ENTER] (from this point onwards all text should be typed
without mistakes as backspace will be read as an input and not an error



5 Type 'MAIL FROM: me@xxxxxxxxxxxxxxxxx'[ENTER] (this can be any


6 Type 'RCPT TO: yourexternaladdress@xxxxxxxxxxx' [ENTER] (must be a
valid recipient address)


7 Type 'DATA' [ENTER] (completes the email envelope configuration and
launches the data input request)


8 Entr some text for your reference, e.g. "test1"


9 Hit [ENTER] then a '.' then [ENTER] again, you should see a
confirmation 'Queued mail for delivery'


10 To exit the telnet session, type 'QUIT'


Hope this helps

Subject: [exchangelist] SMTP codez[Scanned]

I would like to telnet into a Exchange box to test the SMTP server. I am
having issues with some clients who don't get their emails from the net,
so the first thing I did was check over Exchange, SMTP, the logs, etc
and didn't see any errors or issues. 


I then tried to send them an email via Hotmail, they got it. I tried to
send them an email from my own Exchange server... Been waiting 5 plus
minutes for it to arrive.


Anyhow I have a bad feeling that IMF maybe setup too secure but I want
to Telnet to their box first and try sending an email manually; I just
don't remember all the codez and steps to use.
