I recommend that you open a ticket w/ Sangoma and ask them to analyze the
traces. The critical thing is to find out if these are false positives,
phantoms, or stuff actually coming down the line from the carrier. I think
Sangoma is in the best position to help.

P.S. - Regarding the footer - yes, it is annoying, but if you can't turn it
off then you can't turn it off. I recommend doing what Patrick suggests and
getting a gmail account so that you can be free of the footer spam. If you
*really* want to help us out, I'd say investigate the Mailman project and
see if it has a feature that can auto-strip the junk off of the end of an
email. :)
