Our email servers will give incoming mail servers the option to encrypt the connection using TLS (Transport Layer Security), so that your data is better protected from those who might want to want to try and read it. We can also enable the same feature on outgoing email should a client require it ( older email servers aren't always properly configured for encryption so this part of the feature is only enabled on request). - This feature is part of the Email Server Module and was added to all our systems on 1st March 2006.
