[Bug 659975] [NEW] mailman breaks CC field incorrectly

[Satish P]

Public bug reported:

Binary package hint: mailman

Scenario:

When we send an email to a mailing list in either To: or Cc: header and
an address in Cc header with unquoted display name, mailman breaks that
into couple of addresses. For example:

To: user1 at domain1.com
Cc: mailing-list at domain1.com, display name <address at domain1.com>

It becomes:

Cc: mailing-list at domain1.com, display, name <address at domain1.com>

This is wrong because "display" becomes a different address. There seems
to be bug in /usr/lib/mailman/pythonlib/email/_parseaddr.py.

Same bug is reported in Debian and Redhat as well for 2.1.9 version of
mailman.
