Support spam scores and actions for SMTP AUTH outbound clients
Prior to this release spam scores and actions were only effective on non SMTP AUTH outbound clients.
With this release, the options are now effective for both SMTP AUTH and non SMTP AUTH outbound clients.
Support for restricting outbound sender domains
Prior to this release it was possible for outbound clients to send mail using any sender domain and it was not possible to restrict the sender domains to the ones configured for the organization.
The above could be abused by outbound clients forging their sender addresses.
Allow any sender domain option has been added to relay settings
to allow for enabling or disabling this restriction.
To allow outbound clients to send using any domain name the option should be checked (default). This emulates the existing behaviour of the system.
To restrict the outbound clients to using only the sender domains configured for the organization this option should be unchecked.
