Hi Phillip,
this surely gets not to dovecot, my first tip goes to procmail
http://pm-doc.sourceforge.net/pm-tips-body.html search  Order of the
procmail recipes
use google duplicate procmail
after all you can double mails with filters like amavis, clamsmtp
therefor your have to include  -o
receive_override_options=no_address_mappings, in master cf in the filter
after all apple mail has long list of bug with imap with double emails
too, look at you mail log and you will find the reason
