Malformed message-id with sendmail

[Screbinodus]

I am trying to use the sendmail script step while specifying the SMTP server.

The mail get sent OK, however the message header isn't formed correctly. The message-id is something like:

Message-ID:

i.e. without a server or a domain.

This means that many (most?) spam-traps block the mail as suspicious -- a malformed header under RFC 2822 guidelines. Here's an example from a Baracuda server:

////////////////////////////

X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.2.24334

Rule breakdown below

pts rule name description

---- ---------------------- --------------------------------------------------

0.01 INVALID_MSGID Message-Id is not valid, according to RFC 2822

////////////////////////////

I've tried running the script on FM10.3 client on a PC running Windows 7 and a Mac running 10.5, with the same results. Our mail server is MS Exchange 2003.

Has anyone else encountered this problem? Is it a fundamental bug in the sendmail script step, or a specific problem when interacting with Exchange?

Any help or comments gratefully received!

Jon.
