OK, not sure what happened, my response was rejected by Centos:
Reason: There was an error while attempting to deliver your message with [Subject: "RE: Mail has quit working"] to centos@xxxxxxxxxx. MTA p3plwbeout03-06.prod.phx3.secureserver.net received this response from the destination host IP - 208.100.23.70 - 554 , 554 5.7.1 Service unavailable; Client host [72.167.218.218] blocked using ix.dnsbl.manitu.net; Your e-mail service was detected by mail.ixlab.de (NiX Spam) as spamming at Tue, 24 Jul 2018 11:45:20 +0200.

So, I'm trying a third time:

This is pointless because he's complaining about cron and system emails
which use the sendmail command are submitted through the pickup service,
not port 25/smtp (in fact, if you're submitting any mail via port 25
you're doing it wrong but that's another discussion).
TE Dukes:
Please do the following (lines that start with # should be run as root,
lines that start with $ should be run as a local user):
Install the mail command which is an easy interface to the sendmail
command and thus the pickup service.
# yum install mailx
# tail -n0 -f /var/log/maillog
....then in another window (replace someuser@xxxxxxxxxxx with your own
email address):
$ mail -s 'Test Email' someuser@xxxxxxxxxxx <<< "This is a test"
.... wait a minute for postfix to have a chance to process and send the
message, then break out of the tail command and copy/paste the output
into your reply.
Then also copy and paste the output of the following:
$ postconf -nf; postconf -Mf
If I need any more info after that I'll let you know.
