We restrict the number of recipients in a private message (current setting: max 3 recipients) because of private message spam.
where do you edit the restriction of max. 3 recipients. Can't find the setting.
It would be interesting to know what you would use this functionality for
We created a placebo group for messages.
Added members to the group via the admin tools we deployed.
When we want to send a mass email, we just send email to members of that group using the Actions Menu (and only applicable for the Group Owner/Admin)
Not sure if this logic helps, but maybe can stir some ideas on your end.
