I built a new instance of PIAF on a VM and then replaced Sendmail with Postfix.

But I have broken Fail2Ban email capability. I have verified that Postfix is working.

Is there a simple way to uninstall and re-install Fail2Ban?

Nothing gets logged to /var/log/maillog when I start fail2ban. I have checked the mail.conf and sendmail.conf in the action.d directory. It seems to be okay.

How to debug?
