Problem with Mail::SendEasy and Exchange serverby dracos (Sexton)

dracos has asked for the
wisdom of the Perl Monks concerning the following question:
I am having issues with using Mail::SendEasy with our Exchange server. The code I am using worked fine on our old Lotus Notes server.
My IT people and I used an ethernet sniffer and found that the script is sending the "EHLO main" command and getting a valid response(see below). Then the send mail fails returning "Authentication error". Then the SMTP session times out.
The "Authentication error" does not make any sense. The only authentication we allow is based on IP address there is no username/password authentication used.
The funny thing is if I change the string to be HELO instead of EHLO I can send mail with out a problem.
Does any one have any suggestions as to what to do?
Using a telnet client connecting to port 25 I got the following responses form the old Notes server
And this is what I get from the Exchange server
