+  Verify hostname when sending emails via SMTP server with `SMTPSClient`.
+
+  The SMTP server's certificate and hostname must be verified if
+  encryption is enabled with SSL verification in the host settings
+  (`sendemail.smtpEncryption` and `sendemail.sslVerify`).
+
+  `SMTPSClient` from Apache Commons Net used for SSL processing.
+  It has the following downside: if encryption is not required,
+  `SMTPSClient` is used in 'explicit' mode with the upgrade to TLS
+  never called. Thus, the client is somewhat misused.
