Alleged new features? Naw... suggestion maybe...
I think Exim should implement a call-out API so this kind of stuff can
be left out of the core system. Kinda like Exim calls smtp_mail_from()
after it receives a "mail from" command, and the user can supply a
smtp_mail_from() written in users favourite language. See the INN callout
API system for perl and tcl, for an example.
