Emclient(freeware) compared to other similar paid softwares and freewares has more features than any others.I have compared it with Postbox,the bat,gc mail and foxmail and it tops all of them in many ways. Some of it's best features,i liked are -- 1.Notifications for new mail near system tray,which can be configured as how many sec's it will appear. 2.Categories for messages. 3.Custom contact views. 4.Theme support 5.Read mails become dull after they have been read.(doesn't happen in postbox) 6.Import contacts from thunderbird,ms outlook,ms outlook express 7.Synchronize messages with gmail in Imap protocol. and many other features,-- emclient.com/features
