6.2.11 Doing VERP with Exim and Mailman</A>
54
VERP will send one email, with a separate envelope sender (return path), for
55
each of your subscribers - read the information in
56
<span class="file"><var>$prefix</var>/Mailman/Defaults.py</span> for the options that start with VERP.
57
In a nutshell, all you need to do to enable VERP with Exim is to add these lines to <span class="file"><var>$prefix</var>/Mailman/mm_cfg.py</span>:
60
<div class="verbatim"><pre>
61
VERP_PASSWORD_REMINDERS = Yes
62
VERP_PERSONALIZED_DELIVERIES = Yes
63
VERP_DELIVERY_INTERVAL = Yes
64
VERP_CONFIRMATIONS = Yes
68
(The director (router) above is smart enough to deal with VERP bounces.)
