@girish Sure that's completely understandable, thanks for the reply.
Given that neither mailman or SYMPA seems straightforward to implement in Cloudron I might revive this thread to add a basic moderation function to Cloudron mailing list. I believe for security purpose this is the main missing feature and the proposed approached may not be too hard to implement with the current backend(?).
What users still won't get is the ability for members to subscribe and unsubscribe by themselves, but an admin can do that manually so at least it is doable.
Another thing that would be nice is to be able to create a list from a Cloudron Group (i.e. mailing list that contains emails of everyone in a group and that gets updated each time you add or remove a user from a group). I don't know how your database works and how easy that might be to implement. What do you reckon?
(Again this can be done manually so not as important as moderation, but just something that would be nice and possibly doable if the info are easily retrievable from the user database in the backend.)
