Security Tab

This tab of the Send Mail action specifies security settings for secure SMTP and POP connections.

Protocol: Security protocol to use when connecting to the remote server:

•	None: No security protocol will be used

•	SSL, TLS, or PCT: Either the SSL 2.0, SSL 3.0, PCT or TLS protocols will be used when establishing a secure connection. The correct protocol is automatically selected.

•	SSL: Either SSL 2.0 or SSL 3.0 may be used when establishing a secure connection. The correct protocol is automatically selected.

•	TLS: The TLS 1.0 protocol will be used when establishing a secure connection.

•	PCT: The PCT 1.0 protocol will be used when establishing a secure connection.

Fallback to insecure ciphers: If checked, will permit the use of less secure cipher suites for compatibility with legacy servers. If this option is specified, the client will allow connections using TLS 1.0 and cipher suites that use RC4, MD5 and SHA1.

Options: Options related to the security protocol:

•	Default: The client should attempt to establish a secure connection with the server. Note that the server must support secure connections using either the SSL, PCT or TLS protocols.

•	Implicit SSL: Select when the server expects an implicit SSL connection.

•	Explicit SSL: Select when the server expects an explicit SSL connection.

Certificate Info

Location: The location to retrieve the certificate from (user store, machine store, or PFX file).

Store name/file: The name of the store to open or the PFX file to retrieve the certificate from (optional).

Certificate name: Friendly name of the certificate to use (optional). Note that the name must match completely, but the comparison is not case sensitive. If no matching certificate is found, the action will then attempt to find a certificate that has a matching common name (also called the certificate subject). This comparison is less stringent, and the first partial match will be returned. If this second search fails, the action will return an error indicating that the certificate could not be found.

Password: The certificate password (applies only for certificates in a PFX file).

Note: The Plink Tunnel action can be used for creating a secure SSH tunnel for use with the SMTP action if your server does not support SSL (only authentication, and not data transfer, is encrypted when using SMTP over SSH).
