then setup fail2ban to manage extrafields
Now that's a very interesting idea, thank you! I will investigate this.
If you don't expect yor firewall to handle 45K+ IPs, I'm not how you
expect dovecot will handle a comma separated string with 45K+ entries
any better.
My firewall can handle that without breaking a sweat. I just haven't
found a way (that I'm comfortable with) to automatically inject rules
into it from a machine on the network.
Doing it via a DNSBL is an elegant solution to the problem, IMO.
I'm agnostic as far as which method you want to use. All I'm saying is
that using dovecot's allow_net facility is as difficult, if not
more so, than letting your firewall handle it.
