Is it possible to use an SMTP server in Clarity that requires TLS?
Release: 16.2
In Clarity 16.0.0 and higher, it is possible to specify the port for the SMTP server (in 15.9.3, the port must be 25).
However, Clarity will not issue a STARTTLS command (regardless of port configuration), so TLS is not currently supported. This functionality can be requested as an enhancement.
Logs may show errors containing when connecting to an SMTP server that requires TLS:
530 #5.7.0 Must issue a STARTTLS command first
