comment Creating a self signed certificate for demonstration purposes on Centos 7 server
@liv2hak Yes, you will be your own CA. Tomcat should use the Java keystore. Follow their documentation for generating a certificate and getting it signed. Sign it with your CA certificate, then import the signed certificate.

comment Cron errors routing to external mail server instead of local
@JPL It looks like someone changed a cronjob to send logs to an external user. The headers indicate that it is not the CRON daemon sending the email.

comment Cron errors routing to external mail server instead of local
@JPL The messages looks like they were generated by the script not by CRON. Check the user's scripts. It may be better to configure your server so the messages can get delivered.

comment PHP Mail Delayed Shared Hosting
@jchwebdev The delay on the first hop from your server. Examine your Exim log, likely /var/log/exim*/mainlog. You can used exigrep to retrieve the log messages for a single email.

comment Have a valid SPF record but still can spoof my email
@MadHatter Yes I reviewed the revised documentation with that clarification. It wasn't clear in earlier documentation, and I believe I encountered implementations that appeared not to make the distinction. Not all implementations handle edge cases like that in a standard manner. I believe that may be why the clarification was needed.

comment Subdomain with different ip on same server
@PrivatMamtora I've updated my answer to provide a possible use. Adding additional IPs won't resolve an I/O bottleneck, but isn't likely to cause one either.

comment Subdomain with different ip on same server
@PrivatMamtora Either of the first two paragraphs would be reasons to add a second IP address for the sub-domain. I clarified the first case. If neither applies, I can't think of a reason to add the second IP address.

Remove or disable ntpdate it may be leftover from an old version. ntp now does everything that used to require ntpdate.

comment Have a valid SPF record but still can spoof my email
Because you included _spf.google.com your policy is likely to be evaluated ~all not -all. You likely need only one of MX, A, and PTR.

comment How to block IP addresses from port 25
It can be easily done in a connect ACL which denies all connections not from the desired IP addresses. I haven't used the McAfee spam solution, but they should have the requisite A and PTR records in place to pass rDNS validation. You can use then block any incoming connection on port 25 not from their domain. (This is should be more reliable than blocking by IP address.)
