Allow posting to mailing list by entire domain(s), even if they are not a member
Some mailing lists are working groups, a division or project members, to which colleagues should be able to mail, although they are not a member of the list.
Currently there's the option to allow for non members to post, which does not block external contacts (and spammers) to send messages to the group. Or make posting moderated for non members, but this requires an unnecessary action and adds delay to internal messaging.
Several solutions are possible:
- Allow for same domain posting (checkbox)
- Allow for posting by any Kerio user (as proposed in 9962388-mailing-list-scope)
- Option to add a (list of) trusted sender domain(s)
- Option to add a (list of) trusted senders (as proposed in 2556267-mailing-list-half-members)
