Hi everybody,

I'm sorry for being always the strange guy with strange errors here but for some reason... I am. On a Mailman installation that was doing just fine for more than a year, I started receiving error messages per email. It happens when mailman daemon archives a messages. Although the messages is correctly archived, this exception is thrown by Hyperkitty:

I upgraded both to Debian 11 (from 10) and to latest versions of Hyperkitty, mailman-hyperkitty and mailman but still getting the error. Other installations with same specs I'm managing to do not encounter this problem. Any clue of what could have happened, why and how to fix it?

The exception is thrown in the Python email package on HyperKitty's attempt to get the From: header of the message. This looks like https://bugs.python.org/issue43501 and/or https://bugs.python.org/issue30988. These issues refer to display names beginning or ending with a dot. Is that the case with the From: header of the problem messages?

Note that display names containing dot should be quoted.

It appears that at least one of the people posting posts with the problem From: header.
