ipworkssmime_ssmtp_get($res, 28 ); ipworkssmime_ssmtp_set($res, 28, $value );
This property specifies the IP address (IP number in dotted internet format) or Domain Name for a mail relay through which messages will be routed. It is set before a connection is attempted and cannot be changed once a connection is in progress.
The current version of the class does not provide a default value for the mail relay. You must provide a host name yourself. Generally, any internet host with an SMTP server will suffice (a UNIX host for example), but it is preferable to select a MailServer that is close to the machine sending mail.
If this property is set to a Domain Name, a DNS request is initiated and upon successful termination of the request, this property is set to the corresponding address. If the search is not successful, an error is returned.
If the class is configured to use a SOCKS firewall, the value assigned to this property may be preceded with an "*". If this is the case, the host name is passed to the firewall unresolved and the firewall performs the DNS resolution.
