In my Odoo Log I see this:

2015-10-22 18:19:54,641 17416 INFO inline2 openerp.addons.mail.mail_thread: Routing mail from The Intronis Team <respondto@intronis.com> to carlton@inlinetechnology.com with Message-Id <1045679592.53502885.1445537970092.JavaMail.root@abmas01.marketo.org>: direct alias match: (u'res.users', 6, {}, 1, mail.alias(8,))

Where do I look to figure out what is happening?
