I am using a QMT as a smarthost for sending mail -- to be used when any
of my other servers are blacklisted while I get the blacklist entries
ONE user (and only 1 user) is getting bounces of the form:
Hi. This is the qmail-send program at <SMARTHOST FQDN>.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
Delivered with authenticated connection to
<IP Address> does not like recipient.
Remote host said: 553 sorry, your envelope sender has been denied (#5.7.1)
Giving up on <IP Address>.
--- Below this line is a copy of the message.
The "smarthost" receives the message on port 587 (submission) with an
authenticated user (used solely for inter-server communications) login -
thus the "authenticated connection"... but the error says there is a
problem with the "envelope sender" and I'm clueless how this is
different or unique for this one user.
Unfortunately, neither set of log files seems to shed any light on this
-- or else I'm looking in the wrong place.
Any ideas anyone?
