Added:
"OPTIONS=-4 -named" to /etc/sysconfig/named, disabled ipv6 per interface, created /etc/modprobe.d/ipv6_disable.conf file with alias net-pf-10 off alias ipv6 off options ipv6 disable=1
but still getting the same error message.
Maybe it just needs a reboot (which im trying to avoid)

Hi,
from man yum.conf:
              ip_resolve Determines how yum resolves host names.
`4' or `IPv4': resolve to IPv4 addresses only.
`6' or `IPv6': resolve to IPv6 addresses only.

I would suggest looking at the mailer daemon logs on both the sending and receiving systems. It would appear that the sending system is having difficulties at the receiving system end.
You will likely find the root of your issues in the log entries for that message (or those messages) that occurred over the 5 days in question.

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.

Check your /etc/fail2ban/jail.local /etc/fail2ban/jail.conf.

parameters in sendmail-whois or mail-whois actions for enabled jails.
os.org/mailman/listinfo/centos

????????? ????????,

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.

Robert,

If you never changed fail2ban defaults you probably had email aliases 
defined somewhere in your configurations. Whatever you had it was 
incorrect and it's not worth the effort to figure out why it ever worked 
if at all. The "right" way is to use email addresses in (at least 
locally) routable domains.
