OT sendmail header removal

There are some source code edits in google YMMV but I would go about this.

If I had to do it and bend a few RFCs as a result, I'd do it via a milter, MIMEdefang using a bit of perl is probably simplest.

Suggest informing the clients of mxlogic's broken attitude.  What an 
ironic name for a company.  Can't say I would have much faith in their 
services.

You might have more luck asking your question on a sendmail list though.
