perhaps the two problems are related, that ZMailer is being
confused by an unsolicited response and mistook it for the
response to the MAIL FROM?  (I guess this is why some mailers
like to issue RSET :-/ but the ZMailer docs say RSET behaves
differently on different systems; perhaps we could try to issue
NOOP...)

(The first mail is ok; the second mail tries to use the reused
connection, fails because of the 554, bounces back, and is
ultimately not delivered.)
