I have Alfresco Community set up with multi-tenancy. How do you configure a separate outgoing SMTP server for each multi-tenant domain? Is there some kind of global properties file for a domain?
the OutboundSMTP subsystem does not support different server configurations for different tenants. In general, the subsystems are never tenant-specific, unless the subsystem itself has special handling for this (most don't). All mails will always be sent via the same SMTP server.
