I'm trying to set up K9 on my Incredible and am having one little problem (so far). I'm trying to set it up using IMAP. When I set up the account, I chose Push (though I don't see that option anywhere now that the account has been set up). I also have polling off. That still seems to be checking email and notifying me upon arrival of new emails. What I'm having trouble with, though, is it's not syncing correctly with my server. If I delete/mark read/etc an email on the server, that doesn't get automatically reflected in K9. That's how IMAP is supposed to work. If I delete it on K9, it does immediately delete it off my server. Any idea what I might be missing? Also, is using K9 w/Push going to be tougher on the battery than using the Gmail app?
