SSL stands for 'Secure Sockets Layer' - this works by using a public key to encrypt and protect the confidentiality and security of data being transmitted between your email program and our servers.

There are a few things to be aware of with SSL connections:

• SSL (encrypted) sessions only encrypt the connection between your machine and our servers - we then would still have to send the email on to the recipient unencrypted. If you required a secure end-to-end solution then digital signatures and full encryption of your emails is recommended.

• If you are mainly concerned with protecting your AuthSMTP username / password - most email programs will already use methods like CRAM-MD5 to encode / encrypt the username and password.

• Messages sent using SSL cause much greater load on our servers, may be slower to send and are not recommended for high volume use (mailing lists etc.) or from trusted locations.

• Due to the extra load SSL causes - messages sent using SSL will be counted as 'double' wth regard to your quotas - i.e. 1 message of 30k sent will count as 2 messages with a total size of 60k when sent using SSL.

To enable SSL functionality for your AuthSMTP account login to the Control Panel.
