I’ll have a go at that if I get time. For me, the big win for spam prevention with mailing lists is the restriction on posters: it’s what keeps mailing lists relatively spam free. Most sites don’t like to bounce messages that they’ve previously accepted, so that means that the spam gets held for moderation, which creates a lot of work for list owners.

Git mirror for mailman
by Abhilash Raj 20 Mar '14

20 Mar '14

Hi all, I was in a conversation with Barry yesterday to setup a unofficial git mirror for mailman since there are large number of people who use git as their primary vcs. I think it would encourage more people to contribute to mailman, if not through merge requests on lp, through small patches making of which is quite trivial in git I suppose. I am willing to maintain the mirror but I need I don't have a private server to host it. Anyone has ideas about how to setup? or already has a mirror running? Thanks, Abhilash

The main reason I never did was because I couldn't quite work out a nice way to display multiple reasons given the rules for template interpolation. You'll notice the postheld.txt template has a single *indented* line containing $reason and that has implications for exactly what kind of string can go in there (e.g. if it's multiple lines, who's responsible for getting everything to line up correctly). Maybe that shouldn't be indented, but then the wrapping rules might interfere. If you can work out the display issues, keeping in mind an i18n'd postheld.txt template, and the fact that those templates can be replaced by a site or list admin, then I think your basic plan is on the right track. Cheers, -Barry

MM3: message held reason
by Aurelien Bompard 17 Mar '14

17 Mar '14

Hey! On Mailman3, every "message held" notification has "XXX" as the reason. This comes from the HoldChain class in mailman/chains/hold.py, where "XXX" is hardcoded. I'd like to fix that. I think there could be a list in the message metadata to which each matching rule would add a short description of why it matched, like we currently have a list of matching rules in the msgdata['rule_hits'] variable. I'll make sure to mark these descriptions as i18n strings. Are you OK with that? Any trap I'm not seeing? Aurélien

For example, make the NonMember rule exit > if a member is found amongst the senders (which would simply be > equivalent to making it yield to the Member rule). Bad idea? Offhand I'd say that having both a Member rule and a NonMember rule is a bad idea. There should be one conceptual test: can we identify a member as the originator of this post? Having Member and NonMember rules that can both "succeed" is not coherent. I think that what should happen here is that the Member rule should try to identify the originator, and the NonMemberModeration (if in effect) should just check for a "member_identified" property. The member_identified property could be a Boolean or actually contain a list of members (list because it's not obvious what to do if each of From, Sender, and envelope sender corresponds to a different member; that would probably be a policy issue). I don't really see how order dependence can be avoided without violating DRY all over the place. Alternatively, NonMemberModeration might not be a rule, but rather a chain. Perhaps that's the most elegant solution, as order dependence between chains is necessary.

[GSoC 2014] Proposal for Cordova App for GNU Mailman Admin Interface

I like this one: https://bugs.launchpad.net/mailman/+bug/881320 Requires knowledge of gettext and the Python facilities for dealing with it (IIRC xgettext knows about Python now). I recommend searching Launchpad for the "mailman3" tag; Mailman 2 bugs are somewhat likely to be harder bugs, and definitely solving Mailman 2 bugs is not as useful for learning Mailman architecture and coding -- not to mention requiring you to check out and find your way around a rather different source tree. HTH, I gotta get back to work...

[GSoC 2014] Proposal for Cordova App for GNU Mailman Admin Interface
by Bhargav Golla 16 Mar '14

16 Mar '14

Hello After feedback on the mailing list regarding various doubts and questions I had, I have developed a proposal for Cordova App idea and have attached the same with this mail. I would be very much obliged if someone could share their views about this. Also, I have observed on the PSF GSoC page that it requires students to submit a patch to the sub-organization. I was wondering if I could receive any pointers regarding any issues that were highlighted for GSoC aspirants to solve during application period. If there is such, please provide me the information about it or I would be very much grateful if I could get any information about which issues I can target before the application period ends.
