Bug Description
Cyrus is unable to receive some 8bit mime messages from MS Outlook 2016 and/or modern Apple / other mobile clients.
They are rejected with this error message (it would REALLY be nice if an extra patch also added /what/ header and octet offset the issue was from).

This page seems to indicate that the issue might have a resolution in the 3.0.x stable release of cyrus-imapd:

I have tried disabling 8bit mime support in exim4 as well, but it seems to be insufficient to resolve this issue.
