What if sender is a network?

[Tevfik Ceydeliler]

Hi,

I try to configure smtpd.conf file
I have some conf line that works successfully like that:

accept from source { 10.65.8.100 } sender { "@test.com" } for domain { 
anothertests.com } relay

It is OK for one IP address. But I try to do  with a subnet such as 
sources is 10.65.8.0/24 or range from 10.65.8.1 to 10.65.8.255 . How can 
I to do it?

To do, should I enter 255 IP address one by one or is there any other 
parameter?

regards,
