The first version couldnt talk to my mail server. I gave ibis an account & they got it working. Nice tech support! Im still having some trouble with one account that has 100s of IMAP folders. I cant tell if this is the app & I havent debugged yet. Ill update when I learn more.
The app is quite slow for me. But it seems to work well otherwise. Not yet everything I hope for, though.
