So I decided to delete his account and reinstalled it on the IPhone, since that it works without error. Unfortunately now I switched to the latest hg version so I don't have the affected imap binary any more. But I have the core file from the latest crash. If you would like I can send it to you off list. Many Thanks Urban

[UPDATE]: Another Crash in service imap with version 2.2.13 - Debian Wheezy
Hi, short update. I switched back to Debian Squeeze. Same Dovecot Version 2.2.13. The crash happens also on Squeeze. Very strange is that the crash don't happened yesterday. And it happens only to one certain user. Other users with the same iOS os-version=7.1.1 (11D201) aren't affected. Also very strange is, that the crash doens't happen every time (I don't saw that before). Logs in cronological order from the last attempt: ...
