sendmail header removal

[Randal, Phil]

Be careful....  If you start removing Sendmail's "Received" headers
you're likely to break Sendmail's mail loop detection.
 
Been there, done it, got the t-shirt :-)

Subject: sendmail header removal



I've got a couple sendmail/mailscanner boxes that we use to front end
our exchange boxes inbound and outbound.  We've run into a problem with
any email going to mxlogic.net's clients as they do a deep header
analysis and find private IPs in the headers and then the block based on
that.

 

This has happened multiple times and we always have to involve the
receiving customer in the conversation with mxlogic to get it fixed on a
per domain basis, and then months later it just comes back.  They know
they're not supposed to block based on that, but they really don't care.

 

So, what I'd like to do is find a way to rip out the private IPs of the
message headers when we send them, or massage them into public IPs.  Is
there any way to do this with sendmail?
