Package: mailman
Summary: postfix+mailman+postfix-to-mailman.py breaks when
recipient_delimeter="-".
This bug was reported to Ubuntu as
https://bugs.launchpad.net/ubuntu/+source/mailman/+bug/529349
a. Install postfix, mailman packages
mail to user+...@example.com <user%2b...@example.com> should be
delivered to u...@example.com
(because default postfix recipient_delimiter="+")
b. Configure mailman according to instructions in
/usr/lib/mailman/bin/postfix-to-mailman.py
i used a subdomain -- lists.example.com
create a test list using a newlist.
mail to t...@list.example.com should be delivered to your list.
mail to test-ad...@list.example.com should be delivered to the list
admin.
c. change postfix recipient_delimiter to "-".
(add recipient_delimiter="-" to /etc/postfix/main.cf)
restart postfix
mail to user-...@example.com should be delivered to
u...@example.com
mail to test-ad...@example.com will be erroneously sent to the test
list. postfix sees the recipient delimiter and strips it off before passing
it to the postfix-to-mailman.py script.
d. apply attached patch.
postfix will now pass the pre-processed email address (no
recipient_delimiter stripping) to postfix-to-mailman.py.
mail to test-ad...@list.example.com will now correctly go to the
list admin.
