Some odd things were experienced here when the 'mbox smtptoo on' is
present on the JNOS2 AX.25 forwarding chain toward us.
The newest resync'ed JNOS2 version is the most free as for the minor
bugs and for features and stability so it should be the 'only'

As per my understanding and per my knowledge the above loop may be
caused by an 'r' (rescan command) found at the very beginning
of the 'rewrite' file, and so:

JNOS rescans the rewrite file from the beginning, attempting to
match the new destination address with one of the templates.

... and never finding its 'destination' as per the above statement.

Furthermore, the rewrite file contains data used to cause SMTP
to deliver to a specific location.

The result of rewriting determines whether:

- an incoming message is stored in an area (and, which area receives
  the message);
- an incoming message is stored into /spool/mqueue for handling by

The rewrite file, through SMTP, performs a one-to-one mapping between
a message's destination (the “To:” field) addresses as received by JNOS,
and the special destination addresses (public or local areas) as
actually used by JNOS.
The “To:” field text is not modified by the mapping process.

Hope to add some ideas to solve the problem.
