| 24 | To avoid backscatter on mailman instances use the following parameters |
| 25 | {{{ |
| 26 | subscribe_policy = 2 |
| 27 | respond_to_post_requests = 0 |
| 28 | reject_these_nonmember = [] |
| 29 | generic_nonmember_action = 3 |
| 30 | forward_auto_discards = 1 |

| 33 | Also make sure the owner addresses have trust rules for mail coming from mail-man, since all (bounce) spam gets forwarded to the address. If you for example use a free account at BigCorp, you end up getting your mailman instance blacklisted in RBL rules due to backscatter SPAM and 'spammy' forwards. |
