Is there a zimbra-approved way of configuring a maximum number of recipients per message?
For example, spammer/salesman tries to email his latest leaflet to every email address he has ever seen - spammer adds 50000 recipients to his email and sends it off. Salesman then calls to ask why emails are coming back with "blocked" RBL errors.
Im pretty sure "smtpd_recipient_limit" in postfix does this fine, but should a zimbra tool be used to add this, or is it ok to just wade into main.cf and edit? This is currently set to 1000 (postfix default afaik) which for this situation is too much.
Thanks for any tips etc!
