I have several emails set up including gmail account and a work POP email. Sometimes when I send a mail from the work POP address (even by way of a reply from the correct mailbox) the sent mail then appears in the sent boxes of both the POP and the gmail. (there is no bcc enabled) Then, when a client replies it always goes to the gmail address, meaning A: The reply Im expecting goes into the wrong mailbox B: the client now has my personal email address. I have double and triple checked, and on the iPhone the account the mail was sent from is definitely the POP and not gmail. Apple don't have a solution at present. Amy ideas?
