Enable SSL SMTP
Canaille can only support insecure SMTP and SMTP with StartTLS, but not support SMTP with SSL.
This change is used to enable SMTP with SSL.
- Add a SSL configuration in section "SMTP";
- When SSL is set to true, using SMTP_SSL instead of SMTP of smtplib;
- Otherwise, follow the previous logic.
