For 12 connection on amavis, I setup postfix master.cf to have the same
process number. And postfix, amavis everything is localhost.
For 20 max_server numbers on separate amavis1 server, I didn't do anything
on postfix master.cf side. Is that causing the problem? Should I match that
number too?
And I don't know where I setup 1200 seconds.

Can you help me to pin point the problem?
Can this be a DNS related problem? Does amavis server need to have the
correct DNS server setup? (the same one as the postfix server is using?)
I only made host file to point postfix server hostname.
I just want to have my postfix server to accept legitimate emails even some
spams and pass it to another server for spam filtering and then recieve back
and deliver to the maildir on postfix local disk.
On my postfix localhost where 12 max_server is configured amavisd-nanny
shows:
