	Yes it should -- and my local copy does (but it does a lot
	of things that yours don't..  A dump coming up.. see below.)

	What might be the MTA where the sending was attempted ?

	That is, it reports the  SMTPSERVER's  complaint that illegal
	(non-quoted) address is tried to feed to it, but then it states
	below that "554 QUOTED_ADDRESS...  Remote protocol error"

	I have a feeling that the problem side is some  smail, or  sendmail...

	This is "a cake on a face" bug...

Remember that Zmailer in interactive mode has a SH-like shell, which
means that quotes are special characters, and they must be quoted !

Recently I rewrote large parts of the  .cf-scripts to make sure they
will always preserve quotes and dollars properly.

No wonder it blows, try:

	router  '"lao::louis andrews"@mts$.enet.dec.com'

....

	Yes :-)
	Of course it wasn't the way what USER expected...
