remove the "no_more" in the router

Can't help with this. I don't "feel" any performance impact, so I did
not see any need to make may setup more performant.

Hmm, my script does not depend on envelope-from. The only place where I
wrote about envelope from was in the reinjection: Here I explicitly
*set* an envelope-from to my liking.

An envelope-from must allways be present, this is a requirement of the
SMTP protocol. The envelope-from have to be a valid <email-address> or a
empty one <>. Anything sending via SMTP and not including MAIL FROM:<..>
is broken.
