[List admins] Re: Spam prevention

[MarcoAurelio]

 Hello,

Have you tried with header filters at <
https://lists.wikimedia.org/postorius/lists/wikipedia-en-editfilters.lists.wikimedia.org/header-matches/
>?

E.g. you may create a filter for the X-Spam-Score header added by
SpamAssasin, and set a value such as [^+]*[+]{4,} so all emails with a
x-spam-score value equal or more than 4 get rejected/discarded (at the
admins' wish).

I don't quite remember right now, but I think mailman3 header filters do
apply to subscribers as well, even if their moderation policy is set to
"accept immediately", as apparently these rules seem to apply on top of
every other rule/setting and one must be careful, but a SpamAssasin value
of 4 or more should be pretty safe/accurate though.

What I miss in mailman3 (and existed in mailman2 IIRC) is the possibility
to hold for moderation messages from new subscribers only (getting
automatically removed from the moderation queue after X days and/or Y
accepted posts), instead of the current all-or-none approach (I've been
looking for that option but it seems not to exist anymore).

Best regards, M.

[List admins] Re: Just asking

[MarcoAurelio]

Sorry, but I have to object to the previous reply.

I do not think we should somewhat tell fellow list administrators to
'go away, ask elsewhere' especially when we've just migrated to use a
new and unknown software for most of us.

The question posted is legit, and subscription to this mailing list is
now voluntary given that a new listadmins-announce exists [1]. People
is now free to unsubcribe from this one. The footer is no longer
accurate.

Thanks, M.-

Re: [List admins] Help with spam configuration and regex filtering

[MarcoAurelio]

Thanks Milos,

However I've read that mailman uses python regexes to work so I'm still not
sure, taking into account that the instructions on the very mailman config
page difer a bit.

Oh, and I forgot to mention that <
https://wikitech.wikimedia.org/wiki/Mailman#Spam_scores> is the advice I
followed on 1)

Regards, M.

[List admins] Help with spam configuration and regex filtering

[MarcoAurelio]

Dear colleagues,

I am writting to you all because I have doubts as to how to correctly
configure some variables on some mailing lists I administer.

1) Spam

As noted on <> I added "X-Spam-Score:[^+]*[+]{4,}"
at VARHELP=privacy/spam/header_filter_rules. Is that correct? I note that
the header format is like "X-Spam-Score: 6.7 (++)" with numbers and
curve brackets. Is that regex correct to match this?

2) Regex for filtering senders

We've got some email addresses from the same domain banned in
VARHELP=privacy/sender/discard_these_nonmembers. To avoid the list to grow,
I was thinking on using "^.*@banneddomain.com" but I'm not sure if that'd
work. Could you please advice me here?

Thanks for your help.

Best regards, M.

Re: [List admins] Removed myself as owner of the pywikibot* mailman lists

[MarcoAurelio]

Totally understand. Does Mailman have active development currently? If not,
maybe we should consider moving to other mailing list system or develop our
own?

Re: [List admins] Cant login to list

[MarcoAurelio]

Not sure if that'll the best place but I've added at <
https://meta.wikimedia.org/wiki/Mailing_lists/Administration#Lost_list_administrator_passwords>
what listadmins should do if they loose their passwords. Maybe that helps
for the future, but IMHO we shouldn't be hostile to the random request for
help we receive at this list. Just my two cents.

Best regards, M.
