There are several advantages to using an SMTP relay at the IIS WorkflowGen server:
-
Better performance, since messages are sent directly to the relay.
-
Local SMTP acts as a buffer to avoid loss of emails if the main SMTP server is not available.
-
Connection problems are reduced because the relay manages communication problems.
-
The relay traces email deliveries in its own log files.
-
The relay allows you to limit access to WorkflowGen.
-
The relay supports SMTP authentication and encryption (TLS encryption) to connect to your Exchange SMTP (or other mail server).
