Determines if SSL is used.

A SmtpSecurityEnum enumeration.  

object.Security [= value]

The Security Property syntax has these parts:

The settings for value are:

Constant		Value	Description
	SecurityNone	0	No security/SSL required.
	SecurityAllowed	1	Security/SLL is allowed, but not required.
	SecurityRequired	2	Security is required.
	SecurityImplicit	3	Implicit security through SSL wrapper.

This property defines if wodSmtp will require SSL encryption to be used when it tries to deliver the message. You should set it to one of constants defined in SmtpSecurityEnum. It defaults to SecurityNone since most mail servers don't require SSL encryption.

When set to SecurityAllowed, then wodSmtp will try to negotiate SSL using STARTTLS command, but will not require SSL for posting a message.

If SecurityRequired is chosen, wodSmtp not deliver the message unless STARTTLS command succeeds.

If SecurityImplicit is chosen, wodSmtp will negotiate SSL connection even before any (SMTP specific) data is sent through the socket. Usually, server should be running on port 465 when this type is selected.

If your server requires client-side authentication with a certificate, make sure Certificate property is set.

Note: changing this property will also affect Port property. If you set Security = SecurityImplicit, wodSmtp will set Port = 465. Otherwise, it will set Port = 25.
