Hi

I am using dovecot 2.0.9 on CentOS 6.4

The following error appears in the logs when users connect to the imap server using MACs. All other clients that I tested work fine.

I don't know what to do to allow MAC users to use the system. Can anyone help?

Thank you,

2.0.9 is old what about upgrade to recent 2.1.x, 2.2.x

the latest patchlevel of 2.0.x is 2.0.21 so minimum try upgrade to this, your problem may allready got fixed
