You are trying to find a way to set up user authentication for SMTP server in AxCMS.net.
SMTP user authentication is currently not supported by AxCMS.net out-of-the-box.
There are currently two workaround for this:
- SMTP server can be configured to use anonymous access from specified domain
- Configure another SMTP server with anonymous access as a relay
We might consider addition authentication to SMTP server communication in the future versions.
