I've ran into the same issue once. Stumbled upon it for nearly a month, falsely
blaming LXC.
Recreating a container's rootfs from scratch resolved the issue.
I know not of what caused it to begin with, must've been some kind of glitch.

P.S.
It would be great if you can configure your mail client to not use HTML format
for lists.
