Exchange 2019 Remove server name and internal IP from email headers
-
So this is something I've been asked to look at, this appears possible but the information I've found on this doesn't appear to work or I'm missing something.
Anyone else had to do this?

The instructions seem pretty straight forward. Did you give the send connector enough time to sync, or force it manually?

Yeah so, sorry for not following up. The instructions do work, but spam filters (sophos at least) puts this information back...... some great security there.
Anyways... yeah...
I was able to reduce the hop count printer in message analyzer from 5 to 3, which would remove the information. But the damn spam filter....
So it may be a wash to even consider this.

Spam filter can't be made to drop everything before it? We assume the spam filter is at the edge of your network, so the outside world shouldn't NEED to know about anything behind it.

Can it be, maybe does this use case say to do anything with it, no. Security Scan is what called this out. So remediating the item mentioned is the goal, not "fixing" the issue.
