I am looking for an app that will sync data between Android and Mozilla\'s Thunderbird\'s e-mail client. Data that needs to be syncronised includes: * e-mail (multiple e-mail address's) * contacts * tasks * events E-mails must include received, sent, deleted, drafts It needs to be both both ways: Android -> Thunderbird Thunderbird -> Android It must support multiple devices. (I have a desktop, smart phone and tablet and all need to be syncronised) I am happy to pay! BTW, I have thought of using IMAP instead of POP to keep e-mails in sync. But, as far as I know, IMAP only works for received e-mails and not for sent e-mails.
