MIME-header-encoded ',' splits/cuts "From" header

[Jan Kratochvil]

For mail with a header:
  From: =?utf-8?B?TVVTSUwsIFRvbcOhxaE=?= <email address hidden>

Mailman will decode it as mail address <musil> asking for non-subscribed mail address approval.
$ perl -MMIME::Base64 -le 'print decode_base64("TVVTSUwsIFRvbcOhxaE=")'
MUSIL, Tomáš

The mail comes from some Microsoft crap but it is a bug in Mailman as according to RFC 2047 6.2:
  NOTE: Decoding and display of encoded-words occurs *after* a structured field body is parsed into tokens.
at least according to: http://forums.mozillazine.org/viewtopic.php?t=318281

I am unable to duplicate this. Can you give me more info on exactly how this occurs?

I have created the simple message:

To: <email address hidden>
From: =?utf-8?B?TVVTSUwsIFRvbcOhxaE=?= <email address hidden>
Subject: zzz

Hi

If I instantiate a Mailman.Message.Message object from this, both the get_sender and get_senders methods return the expected <email address hidden> address and if I post that message to the <email address hidden> list where <email address hidden> is a member, it is seen as a member post.

I have noticed now 2.1.12 is pretty old (RHEL-6), I will try to upgrade it to 2.1.18 first, sorry about that.

That may needlessly break my lists, I can live with this bug for now, please close this ticket when you have verified it as fixed.

I didn't notice this was with 2.1.12. I saw mailman-2.1.12-18.el6.x86_64 and read it as 2.1.18 or I would have noticed sooner what the issue was. This is Bug # 702516 and was fixed in Mailman 2.1.15.
