[Bug 589642] [NEW] courier-imap-4.7.0-1.x86_64 Input/output error

[Elan Ruusamäe]

Public bug reported:

courier-imap-4.7.0-2.x86_64 is not usable. says "Input/output error"

apparently build with openssl 1.0.0 is the cause as it works ok with
courier-imap-4.7.0-1.x86_64.

simple test possible
1. install package
2. start courier-authlib service

broken situation:
