### SMTP integration | Allows specifying a set of protocols enabled for SSL connection&#x20;

SMTP integration screen allows specifying a set of protocols for SSL connection. By default the plugin offers `TLSv1.0, TLSv1.1, TLSv1.2`, however, this list is extensible and accepts other protocols&#x20;
