mail server in jail, host pf, and fail2ban

[David Mehler]

Hello,

I've got a pf/fail2ban/jail/postscreen question. I'm running a mail
system in a FreeBSD jail, and on the host system i'm using the pf
firewall. What I'm getting are connections to my jail's postscreen
port 25, what i'd like to get done is to try to get those ips scanned
for on the host and banned by fail2ban and pf.

Suggestions welcome.
Thanks.
Dave.
