Secure Destinations

The Secure Destinations tab allows you to define your hostnames which will only accept SSL connections, whether they be POP3, IMAP or SMTP.

This can prevent DNS spoofing.

The SSL architecture is very strict:

If SSL is demanded and the processed message is plain, it is returned.
If SSL is demanded and the processed message is SSL certified the certificate is validated against the certificate(s) you defined for the host, if the certificate does not match the email is returned
Hostnames automatically adapt - if an incoming message is SSL certified IceWarp Server switches to SSL mode.

secure_dest_dialog

Field	Description
Hostname	Identifies the host that will be secured with certificate. You can use patterns here (e.g. .icewarpdemo.com, or only will work perfectly).
Subject	The entity that is identified by a certificate.
Issuer	The organization or authority that issued the certificate.
Fingerprint	A unique number (or "fingerprint) associated with a certificate. The fingerprint is not actually part of the certificate itself but is produced by applying a mathematical function to the contents of the certificate. If the contents of the certificate change, even by a single character, the function produces a different number. Certificate fingerprints can therefore be used to verify that certificates have not been altered.
Import	Click the button to select a .pem file to add to the system. The Open dialog is shown. Upon selection of the .pem file the certificate is read and the fields populated with the correct information.
