Question: Mail garbled and headings switched
I have an iMac (about 2 years old) running 10.13.3
My mail has started becoming garbled - not all of it. Here's an example.
I'm also suffering from headers being switched. i.e. the header will refer to a different message.
I've rebuilt the mailbox several times and I've restored the system fonts.
I have no problems with the same messages on my iPad and iPhone, which both display perfectly.
iPad Air, iOS 9.2
