Hi,
I'm wondering about the difference between $sasl_sender and $sender in
the SMTP Access Policy Delegation Protocol.
${sasl_sender}
This macro expands to the SASL sender name
(i.e. the original submitter as per RFC
4954) in the MAIL FROM command when the
Postfix SMTP server received the message.
This feature is available as of Postfix 2.2.
${sender}
This macro expands to the envelope sender
address. By default, the null sender address
expands to MAILER-DAEMON; this can be
changed with the null_sender attribute, as
described above.
This information is modified by the q flag
for quoting.
Looks like BOTH is the envelope address. Is the one and only difference
the detail, that $sender could have been re-written by
sender_canonical_maps or by re-writing the null sender address?
So is it right, that under normal circumstances $sasl_sender and $sender
should be most of the time exactly the same (if the user is
authenticated and if $sasl_sender is set)?
