DKIM / DKIM, SPF not forwarding

« on: June 30, 2021, 10:39:14 PM »

So I having the following problem.

Godaddy is out registrar.

example.com is hosted on cloudflare by a website hosting company.
A and MX records point to mail.example.com

Problem is that the DKIM/SPF etc are not functioning so some emails are rejected/denied.
How do I add the TXT info onto the subdomain when the main records are on cloudflare?

Do I ask to the hosting company to add the txt records? can i somehow forward the txt records when mail is routed to the mail server?

SSL / Help! Cannot get rid of expired SSL certificates.

« on: February 25, 2021, 01:22:24 AM »

Keep having issue with iOS devices stating that my certificate is expired.

server: mail.azskin.com on Centos 8

If you use the SSL checkers used by CWP7 everything is listed as fine.

https://www.checktls.com/TestReceiver

if you put in my server it states that 1 out of 3 of the certificates is expired. Unsure how to remove that certificate.

Failures: 5 (sshd)

I am getting hundreds of these emails daily.

How do I suppress this.

I have turned off all email alerts in the csf.conf by setting them to zero and I still keep getting them.
