IMAP Problem after update from RC1 to RC2

[Mischungsmicha]

According to the update from RC1 on RC2, I get an error message when creating subfolders. The IMAP server is not accessible.
Have to control again RC1 installed, and the RC2 with a fresh installation. In RC1 does this problem is not, in RC2, the error message.

The error log, the following written:

Code Select Expand

IMAP Error: Authentication for [email][email protected][/email] failed (LOGIN): "a001 NO Authentication failed." in on line 0

Sorry for this google translated Post:-).
