Greetings! Our organizarion has a need to relay mail to multiple smart hosts based on sender domain. For example, our user mail goes through Office 365, however, we have some applications which route mail through a SMTP provider called SendGrid. We are looking at potentially another smarthost that is in China.
I am trying to get confirmation on whether any of the following are capabilities of Brightmail Gateway:
1. Smarthost Authentication - I see where you enter smarthost information for next hop of outbound mail but don't see a way to provide credentials in the case that the service requires it.
2. Is it possible to have multiple outbound interfaces defined in Brightmail Gateway and assign a particular smarthos to each one?
We are basically trying to avoid having sets of Gateways for each different smarthost that we need to send mail through. Thanks in advance!
