Hi,
c:\telnet <exchange server> 25
Wait for the SMTP header then type (each line after the server responds):
HELO blah.blah.blah MAIL FROM: test@xxxxxxxxxxx RCPT TO: test@xxxxxxxxxxx DATA blah This text will appear in the mail message. <blank line> . <blank line> QUIT
Hope this helps.
Regards Steven
