Hi Nick,
Thanks for the reply. That link is bad but I have gone to the correct
one. What it is saying is that the from address is not locally known so
it will bounce the mail. That is really a symptom caused by the MAIL
FROM not being sent. Since there is no from address, it cannot verify it
and thus puts out that 553. When I look at the complete exchange between
servers, there is indeed no indication that a MAIL FROM command was sent
and that is the crux of the problem. I have a generic maps set up but it
is apparently not used because of this problem. Why is it not sending
MAIL FROM as a matter of course and more importantly, what can I do to
force it? If I solve that the 553 will take care of itself.

The article they link to doesn't exist anymore, but I'm wondering if
you need to be using a certain from address, or possibly a certain
from domain ( ie;
http://www.postfix.org/postconf.5.html#smtpd_sender_login_maps)...
That's what the first line suggests to me..

My ISP has recently changed my mail server so that I am forced to use
authentication. I am using SASL with a hash file. That all seems to
be working. However, I am unable to send mail because for some reason
postfix is not sending a MAIL FROM command. The relevant sequence of
messages I get from my ISP's server is:

I thought a MAIL FROM was always sent. Is there a configuration
parameter I am missing that is needed when using SMTP authentication?
TIA.
