Configuring Your Network For SPX

Sending SPX messages does not require any special network configuration. However, to allow SPX recipients to access the SPX Secure Email Portal, you must ensure that the portal can be reached through your firewall. When secure reply is enabled (using the SPX Template wizard), users can send encrypted responses to the encrypted messages that they receive. The SPX web portal can be configured to use either port 443, or port 10443.

It is also important to note that for the purposes of SPX secure reply, the appliance determines whether a message is inbound or outbound by comparing whether the recipient's domain appears in the list of incoming mail domains. A message to an external recipient may be considered inbound if you have configured your appliance to use an incoming mail domain that is the same as the recipient's domain name. This in turn may affect any policy rules that are configured to use SPX encryption only for outbound messages.

Note
If you have configured the End User Web Quarantine to use one of those ports, only the remaining port will be available for the SPX portal.
