Yes. Custom messages in sender_access
you can't reject sender at HELO stage, because at that stage the
sender is
not known yet.
Well that answers that.
Second, this server is sitting behind a firewall (10.0.2.1). Is there
anyway to get the sending IP address instead of the firewall?
configure your firewall to do destination NAT, so you see the real
source. Hiding real source causes big problems to spam detection.
Did some searching and I'm not finding this. I have been doing
masquerade for outbound connections. I never thought to do it on inbound
connections. I'm having trouble finding out how to do it on firewalld
but I'll keep looking
