No it does not and that's why I have the following:
"Sender address rejected: Domain not found (in reply to RCPT TO command))"
(Have a look at the log extracts I inserted in my original email)
I agree with this error code the remote server sent back to my server.
I know users have to fill in their email envelope with their "good"
domain name in the "mail from" header to avoid this.

Here I just would like to (better) understand the way the deferred mail
delivery attempts work.
