Hello, public mailing lists (even sometimes private ones) are target of non-stop spamming. Some mailing lists decided to discard any mails from non-members (that is not good, LGBT mailing has recently decided this but admins were have to do it because of spams and they don't want this) but some mailing list decided to use moderator (and that causes another problem: I usually receive e-mails with this subject because I'm a moderator in wikifa-l: "Wikifa-l post from xx(a)yy.com requires approval" and the text of the e-mail is the text of that e-mail which is obviously spam, so gmail usually consider this mail as spam and after a while It consider wikifa-l-owner(a)lists.wikimedia.org as spammer and that's bad sometimes that become worse and gmail consider the whole lists.wikimedia.org as spammer) and honestly I'm frustrated of discarding spams We really need to define a method to filter spams. specially a central place to kill every e-mail that has been sent to more than three mailing list or so many other methods. there are several methods [1] Another thing: GNU mailman has introduced a spam-filtering system, but I think we haven't updated to that version and our version is 2.1.13 which is released in 2009-12-22 [2] and last stable version of GNU mailman has been released in 23-Nov-2013 [3]. Is there any reason for not updating?
