Description (last modified by Ryan J Ollos)

When doing any change which should start sending mails, no mails are delivered. Instead I get an error in the logs:

This bug only happens when mime_encoding is set to none, when setting it to base64, mails are delivered as expected ...

Keywords: encoding added; AnnouncerPlugin removed
Owner: changed from Robert Corsaro to Steffen Hoffmann
Priority: lowestlow
Severity: blockermajor

This is a surprising combination, that I can't agree to while aiming at some sane flags.

As you can get around it by choosing a suitable encoding, it's certainly not a blocker for you too.
