   Problems
   
+    * Mailman will send as many MAIL FROM/RCPT TO as it needs. It may result
+      in more than 10 or 100 messages sent in one connection, which will exceed
+      the default value of exim's smtp_accept_queue_per_connection
+      This is bad because it will cause exim to switch into queue mode and
+      severely delay delivery of your list messages.
+      The way to fix this is to set mailman's SMTP_MAX_SESSIONS_PER_CONNECTION
+      (in ~mailman/Mailman/mm_cfg.py) to a smaller value than exim's
+      smtp_accept_queue_per_connection
+
     * Mailman should ignore Exim delay warning messages, even though
       Exim should never send this to list messages.  Mailman 2.1's

+Doing VERP with exim and mailman
+
+    VERP will send one Email for each of your subscribers, read the information
+    in ~mailman/Mailman/Default.py for the options that start with VERP.
+    In a nutshell, all you need to do to enable VERP with exim is:
+    VERP_PASSWORD_REMINDERS = 1
+    VERP_PERSONALIZED_DELIVERIES = 1
+    VERP_DELIVERY_INTERVAL = 1
+    VERP_CONFIRMATIONS = 1
