Sendmail showing internal IP and hostname. How to change?


Hi guys,
Bit stumped on how to disable or modify the email headers showing the internal IP and hostname of the server when using sendmail. I want this removed or change to just a domain name.

Can someone direct me to the right direction on how to do this?

Thanks in advance!

There's no simple way because it violates RFCs to not add a Received header and there is no good reason to do it.
If some auditor is telling you it improves security, then hire a different security auditor.

That said, you can hack /etc/mail/sendmail.cf to change the part that looks like:

Code:
HReceived: <whole bunch of weird sendmail macros>
and then hope you never need to track down an email problem.

Hahaha. I want to but it's not within my power to do so.
But thanks so much for the info. I just need to somehow get rid of the internal IP and hostname from showing up in the header.
