2 Copies of Voicemail Sent via email? imap, etc

Hi All,
Setting up my first Asterisk/Freepbx system here. I compiled asterisk (latest) w/ the imap option and I have it successfully sending email to our imap based system (Zimbra). However it is sending 2 copies.
It’s as if Freepbx is doing it’s thing (attaching message or not, depending upon Freepbx setting), and the imap is sending the attachment regardless.
Does anybody know how to over-ride the built-in, default behavior to use imap only?
