sendmail configuration question

[nosrema]

Is there a way that you can change the Message-ID field in an incoming email to an sendmail server before that email is relayed out to the destination smtp server?

By default the Message-ID displays the local machine name that the email was generated on.
Message-ID: <009b01c3fa6e$ef6a3f10$3701a8c0@internalmachinenam e>

I would like to change that to the domainname of the sendmail server.

Message-ID: <009b01c3fa6e$ef6a3f10$3701a8c0@externaldomainname >

Is there a way to reconfigure that Message-ID on the sendmail server?

Thanks,
Greg

if you want to do it the lazy way, just name your machine the same as your external name. unless you are attached to that name.
