If you are interested in VERP there are two options. The first option is to allow Mailman to do the VERP formatting. To activate this, uncomment that line and add the following lines to your <span class="file">mm_cfg.py</span> file: <p> <div class="verbatim"><pre> VERP_FORMAT = '%(bounces)s-+%(mailbox)s=%(host)s' VERP_REGEXP = r'^(?P<bounces>.*?)-\+(?P<mailbox>[^=]+)=(?P<host>[^@]+)@.*$' </pre></div> <p> The second option is a patch on SourceForge located at: <p> <a class="url" href="http://sourceforge.net/tracker/?func=detail&atid=300103&aid=645513&group_id=103">http://sourceforge.net/tracker/?func=detail&atid=300103&aid=645513&group_id=103</a> <p> This patch currently needs more testing and might best be suitable for developers or people well familiar with qmail.
