You are correct, but this is tricky. The intent of RFC 2047 section 5,
rule 3 is that an encoded word such as
=?iso-8859-1?Q?Mai=2C_G=FCnter?= when used as the real name portion of
an address will not contain any of the characters which are not
allowed unquoted in this context, and this is true of that encoded
word.
However, Mailman looks at the From: header, and because of the way it
processes this, it sees an ascii decoded header value which looks like
'Mai, G?nter <guenter....@lrz.de>'. It then parses this and gets two
email addresses, 'mai' and 'guenter....@lrz.de' because of the
unquoted comma.
For some purposes, such as determining whether a post is from a list
member, Mailman considers all the addresses and will determine that
this is from a list member if 'guenter....@lrz.de' is a member, but
if the post is held for some reason such as 'guenter....@lrz.de' is
moderated, the notice to the user will be sent to only the first
address 'mai' which is invalid.
So, yes, you are correct that Mailman is not doing the right thing here.
I've developed a patch that I think will fix this without any other
side effects. I've attached that as rfc2047.patch.txt. Please try this
patch and see if it solves your problems.
