[Orchestrator] - Potential issue on SSL or TLS secure connection for SMTP server reachability

Actual behavior

It is been discovered that if the variable passed to the mail controller is in CAPITAL, such as below : MAIL_SEC="SSL"

The remote SMTP server won't respond and the query will fail.

It would be potentially justified to put SSL or TLS or STARTLS in lower case within the code.

Expected behavior

SMTP server reachable.

Step by step description of new behaviour

A verification of the ENV variable for the secure methode in order to pass it in lowercase.

Benefits

No risks of mistakes from the end user and SMTP server if AUTH enabled will succeed.

Possible Drawbacks

None.

Applicable Issues

None.
