postfix interacts badly with postfix-to-mailman.py when recipient_delimiter="-"

[butter71]

mailman 2.1.12
postfix 2.6.5
ubuntu 9.10/karmic

setup according to the instructions in postfix-to-mailman.py.

when postfix recipient_delimiter="-", the 'user' gets passed to postfix-to-mailman.py with the trailing -xxx removed. mail to "list-owner" or "list-subscribe", etc gets passed as "list". this breaks anything but mail to the list.

i patched postfix master.cf to send the entire recipient address and postfix-to-mailman to manually extract the username.

postfix_to_mailman.py is neither distributed by nor supported by the GNU Mailman project. This bug/patch should be reported to Debian/Ubuntu since they are the ones that choose to distribute this with their Mailman package.

Note that all of Mailman's default VERP like processing depends on Postfix's recipient_delimiter = +. If you set it to '-' you need to alter some formats and regexps in mm_cfg.py. See http://wiki.list.org/x/D4CE
