SMTP Notifications Using Email Relay

SOLIDWORKS PDM Professional has the functionality to configure SOLIDWORKS PDM to send notifications through the default database message system or an SMTP mail server. Whereas SOLIDWORKS PDM Standard supports only the default database message system. But how do we set up the SMTP Server using an Email Proxy Application? That will be addressed in this article.

Why would I need to use an Email Relay?

There are multiple third-party applications available to use as an email proxy, this article will highlight only ONE of the many open-source applications that will act as the proxy to forward emails from one server to another.

It is the responsibility of users to set up and troubleshoot the setup of the Mail Proxy Server.
