OK; the key bit I missed was that the incorrectly parsed email address was broken over two lines.
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 The posting to the test-list mailing list incorrectly has two emails addresses: Date: Mon, 18 Oct 2010 10:44:12 +0100 (BST) From: [email protected] Cc: three <[email protected]>, [email protected], [email protected] Subject: [Test-list] Test Test Email _______________________________________________ Test-list mailing list [email protected] http://hardy-mailman.example.com/cgi-bin/mailman/listinfo/test-list ** Attachment added: "Test email commands and content" https://bugs.launchpad.net/debian/+source/mailman/+bug/659975/+attachment/1699390/+files/test.txt -- mailman breaks CC field incorrectly https://bugs.launchpad.net/bugs/659975 You received this bug notification because you are a member of Registry Administrators, which is the registrant for Debian. _______________________________________________ Mailing list: https://launchpad.net/~registry Post to : [email protected] Unsubscribe : https://launchpad.net/~registry More help : https://help.launchpad.net/ListHelp
