[Bug 659975] Re: mailman breaks CC field incorrectly

[James Page]

** Description changed:

  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.

  Actual Results:
  
  Single email address in Cc header became two addresses
  
  Expected Results:
  
  Single email address should remain as one address only
+ 
+ TEST CASE:
+ Using a standalone mailman + postfix setup on Hardy I have been able to reproduce using the following procedure:
+ 
+   Install postfix and configure as final destination for <hostname>.example.com
+   Setup three users (user1, user2 and user3)
+   Install mailman and setup default (mailman) and test-list (with user1 as list owner) list.
+   Configure Apache to allow administration of mail lists
+   Install and configure dovecot for local mail delivery.
+   Add user2 to the test-list mail list using the administration screens
+ 
+ Using the attached email (test.txt), simulate the offending use case
+ using the following command using the user1 account:
+ 
+   telnet localhost 25 < test.txt
+ 
+ Address for user three will break into two email addresses
