Hi there! I've been reading the documentacion as well as googling around but I've been unable to figure this out:
I have several hosting servers. I'd like all web sites hosted in those servers not to be able to send outbound mail without authenticating first. Same thing for shell users. What I'm really trying to achieve is that everybody (local accounts and php scripts running under www-data) will be forced to use the submission service (smtp-auth, tls activated) for all outbound emails, keeping non-authenticated connections just for internal emails (usually from services to the system administrator) Any guru willing to point me into the right direction? TIA!! Ignacio
