bug#31590: 25.1; malformed email address in RMAIL

[Olivier]

Hi,

When trying to read the new messages in RMAIL, I get the error
"Malformed email address" on one message (it did happen in the past,
once every 2 years maybe). As a consequence, messages following the
malformed one cannot be read and no message is deleted from the INBOX,
resulting in reading the same messages over and over again.

This time I managed to identify and keep a copy of the
concerned message.

I am reading my mail through POP3, with movemail installed as part of
mailutils-3.1.1_3.

Emacs installation is pretty standard, build from FreeBSD ports.

Trying to read the same message with Thunderbird (POP3 and IMAP) did not
give any error message.

I have been using Emacs for over 30 years and I have always been
completely happy with it, but that bug bugs me.

Attached is a copy of the message.

Best regards,

Olivier
