    • SMTP - Common section, Accept mail ONLY if a connection is secure. If enabled, the DATA SMTP command will be accepted only if a connection is secure;
    • Delivery section, Deliver mail ONLY if a connection is secure. If enabled, and receiving mail exchanger does not support STARTTLS, or if a secure connection fails, mail will be bounced to sender;
    Note, that those options should be used with caution, only when security is a high priority. If they are used unnecessarily, some emails may be lost;

It runs along and with the same "rights" with other services (like SMTP, IMAP, POP3), and can be configured the similar way. No third party servers are required. Currently it is pretty limited: you can only check email, and only in Inbox folder. More, including server administration, is coming in future versions. Both, HTTP and HTTPS are supported;
  • Improved handling of Recommendations, introduced in version Added checking of server certificate, also verifies whether DKIM key pair is set up properly and they match.
