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

EHLO main
250-CHIMAIL1.TMRIUSA.COM Hello main ([xxx.xx.xx.xx]), pleased to meet 
+you
250-HELP
250-SIZE
250 PIPELINING

HELO main
250 CHIMAIL1.TMRIUSA.COM Hello main ([xxx.xx.xx.xx]), pleased to meet 
+you

And this is what I get from the Exchange server

EHLO main
250-chiexc.TMRIUSA.COM Hello [xxx.xx.xx.xx]
250-SIZE
250-PIPELINING
250-DSN
250-ENHANCEDSTATUSCODES
250-STARTTLS
250-X-ANONYMOUSTLS
250-AUTH NTLM
250-X-EXPS GSSAPI NTLM
250-8BITMIME
250-BINARYMIME
250-CHUNKING
250-XEXCH50
250-XRDST
250 XSHADOW

HELO main
250 chiexc.TMRIUSA.COM Hello [xxx.xx.xx.xx]

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
