I have 3 email domains: domaina.com, domainb.com and domainc.com for example.
I would like to send outbound email for domainb.com and domainc.com via WebSense Hosted Email. I would like outbound email for domaina.com to send via MessageLabs.
I created 2 x Send Connectors and added the domains in the Address Space accordingly and routed them through the correct Smart Hosts.
Once I had done this, all outbound email stopped and queued with a error message stating that there wasnt an appropriate send connector for the domain.
What am I doing wrong?
