Uncheck the Refuse NUL.  That will only make things worse for you.
You need to adjust your Relay Options to not allow third party relay
rape.  If they are all coming from one block of IP's then put them in
the Deny Access list under Control Options.
 
I am seeing a huge increase in relay rape SPAM from Imail servers.
This is not good.

Subject: [IMail Forum] Spam Help!

I have been fighting Spam all week from my server. Apparently my server is being used as a relay server and really upsetting some people. My upstream is going to shut me off if I cannot get it under control.
 
I have configured the server to Allow mail to local groups, Refuse NULL <> Senders, Check Valid Sender, Auto-Deny Hacks.
 
It appears that the mail is using ports in the 3000 range.
 
What can I do?
