[SOGo] Sogo as a MTA relay server

[Cezar Souza]

Hello dear,
 
We have an external shared email service and we would like to use Sogo as the 
collaborative tool with calendar and ActiveSync support. 
 
Could someone tell us if it's possible to setup Sogo as a MTA relay server to 
get emails from our external shared email service and delivery it to all 
clients with the calendar from Sogo?
 
Best regards,
Cezar
