I have all my accounts set to IMAP, that way all my sent folders etc are synced with my iphone... I have been having a problem for a while, where.. when I send something from my mac.. and only my mac... multiple copies will be sent out..usually 2 copies show up in sent folder and for some accounts and one instance it was more than that. It seems to happen across multiple accounts. so I do not think it is gotta do with the email hosts.. I have accounts on hotmail doing this.. accounts from zoho doing the same thing... I have no idea where to start looking for the problem. Any help would be much appreciated. Thanks !
