http://www.aqua-mail.com/download/AquaMail-market-1.3.5.apk- Several crash fixes (Google Play reports).
- Don't trust just any IMAP server advertising CRAM-MD5 as a supported authentication method. Use only if it's the only auth method advertised (for tin foil hat types who manage their own mail servers).
- IMAP CRAM-MD5 turned off for @telefonica.net (advertised, doesn't work).
I'm hoping to publish another update to Play this weekend, taking the rollout to a full 100% of users' devices.
