Hi here,
For me I would prefer an iOS (and Android) app to check/answer/send emails, but with a full encrypted protocol for the communication with the server and also if data are stored on the mobile.
I'm not a fan of IMAP, not anymore, for me it sounds like the 90's (but I can understand we still use it), and more if I choose an encrypted mail service I will not store in clear the emails on my local machine, else I will loose in security level.
