feat(postfix): disable processing of MIME headers#1016
Merged
Conversation
Default behavior is processing headers that are actually part of the message body. This is unlikely to be needed as headers such as Received are not added into MIME parts, but may result in broken DKIM signatures if the body is modified.

This setting looks like what we want for simplicity in any case, as parsing nested and MIME headers is unexpected (didn't know Postfix does this). May help with #1005 and https://support.delta.chat/t/how-can-i-access-unencrypted-emails-on-the-nine-testrun-org-server/5474 as there is one less possibility of postfix modifying the message body and breaking DKIM signatures. |

Oh wow, I wonder if this causes any DKIM issues in the wild
