EM-3607
An encrypted connection to the mail server could not be made
Why it happens
Rabt sends email only over an encrypted (TLS) connection, and that did not work with your SMTP server: the server may not offer STARTTLS on this port, or its certificate is invalid, expired or does not match the server name. The full error is in the technical details.
What to do
Check the server name, port and security type in your email provider’s settings (usually 587 with STARTTLS or 465 with TLS), and use the host name the certificate was issued for.
