I need to setup K-9 on my Dad's Droid. I won't have the opportunity to tweak it, and I'm hoping I can get some advice before I do it. He has two gmail accounts. One of which is a shell account for another custom domain email. Since the native Gmail app isn't smart enough to allow for a "Send-As" option, I need to setup another 3rd party app for email that can. A while back I had installed it for him and it was working ok, though he reported some battery life issues as a result. Soon after, the program stopped working (may have been user error - Maybe he had changed his password). It will be set up as IMAP. He also uses Outlook for the same account. He doesn't use gmail's labels very much, if at all, so I really only need the app to get his new inbox mail, and let him access sent mail. If he decides later to start using the labels instead of filing messages in his local PST, I will sort that out then. Right now I am just looking to know the best settings so that his email pushes right away and that it isn't polling all of his folders every few minutes. Do I need to know anything special about folder classes? I wouldn't ask if this was for me, because I can sit and tweak and experiment all day long. I can't align schedules with my father often enough to use that regular approach. Thanks in advance.
