Check your /etc/fail2ban/jail.local /etc/fail2ban/jail.conf.
You have to provide valid email addresses for dest= and sender=
parameters in sendmail-whois or mail-whois actions for enabled jails.

Александр Кириллов,
I should have made it clear that this is all on one machine. The
jail.conf file is the default from the fail2ban package. It used to work
perfectly, but now has the mail problem. All I've had to do for years is
install the fail2ban package, start it, and make it autostart whenever I
reboot. Now it's misbehaving in a way that puzzles me.
