Well... lets try to do this manually and see what we learn:
First of all you need Base64 encoder... you can use whatever you like, but
here is one:
http://www.solidz.com/tools/base64.php. Now, get your username/password
encoded on Base64 and paste them on the notepad.
Start->Run->Cmd and do the following (be careful when typing because there
is no backspace in telnet... but you can use copy+paste in the upper left
corner of the dos window):
Telnet outgoing.verizon.net 25 [enter]
EHLO yourdomain.com [enter]
AUTH LOGIN [enter]
encoded_username [enter]
encoded_password [enter]
MAIL FROM: user@yourdomain.com [enter]
RCPT TO: someone@insomeotherdomain.com [enter]
DATA [enter]
SUBJECT: TEST [enter][enter]
TEST MESSAGE [enter]
. [enter]
QUIT
Do you see an error somewhere?
