Exclude networks in SMTP source exceptions
In the current version (17.5.5) it is still not possible to define whole source networks in SMTP exceptions. It is only possible to select single ip hosts or fqdn hosts.
In a few cases you need to exclude whole /27 networks from greylisting, SPF and more. Very annoying to create single hosts to add.
Very much needed. It amazes me that an "advanced anti-spam" system does not have this ability.
