Maybe I found where is the problem.
Here is the QCF/QDF of a test message in the queue folder of the first instance:

As already seen, this message is moved by an outgoing rule to the
PEC-out mailbox, and sits there waiting to be picked up by Wsmtpex; the
following is the Header of the message found in the CNM file in the
PEC-out folder

We can see that the "Return-path: <pinco.palla@pec.it>" line disappeared.
Now, as stated in the wsmtpex.txt file
[quote]
WSMTPEx looks into .CNM file and search for header 'Return-Path' for
SMTP envelope MAIL FROM address. Uses "<>" if none is found.

So, I was thinking that this may lead to the QCF with the empty "FR: <>" field in the queue of the second instance (and to the subsequet problems).
May this be so?
I'm wondering what to do... Any idea?
Best regards
