Hello Mark,

Sorry, but I didn't immediately spot that you were asking for this type of
information which I am now enclosing below, as requested :
(Reminder : 'domain.org' and 'domain.net' are hosted on the same VPS and
'domain.org' is the virtual domain that has been specified in the
'mm_cfg.py' config file. The declared MTA is 'Postfix'.)  

1) Selected Sequence from /var/log/maillog

Not until you do as I asked before and post the resulting output from
grepping the mail log for the Postfix queue id of a returned message.

Based on your prior post, this would be something like

grep 9F72D11C00A /var/log/maillog

Also it might help to see your transport maps - /etc/postfix/transport
