When there are attachments in an entry, logbook is adding additional "MIME-Version" header to e-mail messages.
Spam filter in our university system is mostly giving warnings:
- X-Amavis-Alert: BAD HEADER SECTION, Duplicate header field: "MIME-Version"
But sometimes it is not redirecting further the message.
- Remote Server returned '< #5.6.0 smtp; 554 5.6.0 Bounce, id=27666-07 - BAD HEADER>'
In code I noticed there is always "MIME-Version" header added to the message and additionaly it is added again when a file is attached. I think it is not neccessary to add again this header. |
