MTA does not run after TLS enabled with no certificate
Last Updated June 04, 2019
Enabling TLS encryption with no TLS certificate selected results in the MTA failing to start.
No errors are logged and the system does not attempt to start the MTA process even though a service restart shows [FAILED]
TLS encryption has been enabled but no certificate selected. Normally this is not allowed in the configuration but when no certifictes exist in Administration > Certificates but a Certificate Signing Request has been created, the Accept TLS encryption checkbox is enabled without the ability to select a certificate.
