Environment
GWAVA (Secure Messaging Gateway)
Situation
It is needed to encrypt outbound email via TLS, how can this be done using SMG?
Resolution
To encrypt outbound email using TLS the following needs to be done:
1) SSL needs to be enabled and the SSL certificates need to be installed on the SMG server. Here's a TID on how to do that.2) Under Module Management | Interfaces | SMTP Interface Manager | SMTP Interface | External Delivery change the Connection security to 'auto'.Auto will send it via TLS to the servers that advertise TLS. It will send it normally to the ones that don't.This can be set to TLS, if it's required to send all outbound email via TLS, but use caution as not all systems have TLS enabled and it will fail to send to the ones that don't.
