overriding output from telnet

[rob@xxxxxxxxx]

I have an email address that is telling us it's undeliverable.  I have the 
auditing set on and I can see this;
83 U <CONTACT.NAME@xxxxxxxxxx>
87 CLNT(UNDELV) TO QTMSINQ 

I verified that the email address is correct.

I played around with 
http://zmailer.org/cgi-bin/mxverify-cgi?DOMAIN=MyCust.COM

Then I picked one of the IP addresses provided and tried this
TELNET ('xxx.xxx.xxx.xxx') PORT(25)

and then did this:
220 *******************************
EHLO fromhere.COM 
502 5.5.2 Error: command not recogn
RSET 
250 XXXXXXXA 
EHLO fromhere.COM 
250-something-this.somethingelse-morestuff.net 
250-PIPELINING 
250-SIZE 209715200 
250-VRFY 
250-ETRN 
250-ENHANCEDSTATUSCODES 
250-8BITMIME 
250 DSN 
RSET 
250 2.0.0 Ok 
MAIL FROM:<me@xxxxxxxxxxxx> 
250 2.1.0 Ok 
RCPT TO:<contact.name@xxxxxxxxxx> 

When I press enter on that last line a message pops up but it whizzes by 
so fast I can't make it out.  It then shuts down my telnet session.
I am just sure this contact name is right.

Warning:  typos are not accepted and cannot be corrected with a back 
space.  So, it took me a few times to enter this right without any typos.
