Is it possible to use an SMTP server in Clarity that requires TLS?
Release: 15.9.3
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.
