Today marks a serious achievement for Treo email as ChatterEmail now supports POP3! While actually still in beta, it’s running very well for me currently with 3 POP3 accounts and 2 IMAP accounts. I have Yahoo and GMail both running in POP and yes that means SSL is fully supported as well since that is required for GMail.
Attachment support is pending so don’t expect to go to crazy just yet. That said you can nicely control both the number of messages downloaded, the amount of those messages delivered (in lines) and also control deletion status. The key feature POP3 clients have been missing is the core strength of Chatter and that is the asynchronous nature of how it works. Running asynchronously means your email can be delivered while in the background of other apps and even with the screen fully off. You can sync your accounts on a set interval (30 min by default, but whatever you like) and know your mail will simply be waiting for you to read it. IMAP accounts can stay connected if you like for the full always on experience.
If you’ve been looking or waiting on features from other POP email clients, Chatter delivers today.
