Setting up SMTP with DxEnterprise Version 17 on Linux

Applies to:

  • DxEnterprise 17.0 for Linux


The following error is logged to the system when trying to configure SMTP on a Mono-based install:

DxEngine completed with status 1  
Journalctl reports Caught exception: System.Net.Mail.SmtpException: Message could not be sent.
SystemIOException: The authentication or decryption has failed
System.InvalidOperationException: SSL Authentication error: RemoteCertificateNotAvailable.


The resolution is to manually add your certificate to the trusted list for the Mono framework.

sudo yum install mono-devel -y  
sudo certmgr -ssl https://your.smtp.server
