Mail Mess

Mail is a mess. Some emails get bounced to mail/new/ folder, and are not delivered. It all started when I dropped some domains. Mail is sent using PHPMailer via SendMail. Here is what I see in one bounced email:

Should note I use CloudFlare CDN. This email originates from the password-sentry.com. Also, is there any way to for lionsgatecreative.com to be replace by domain name where the email is being generated? And, I have an issue with Mail HELO. It is set to one of the domains I dropped, but cannot change. How change, and is it possible to use different one for each domain? Each domain is a separate account.

What's the output of the following: exigrep 1jWnwJ-000HPd-4I /var/log/exim_mainlog
(just rename any local domains/IP's)

I'm not sure I understand - this sounds like it's coming from a service not associated with the cPanel account am I correct?

What's in /etc/mailhelo
?

Gotta apologize. Figured out what was happening with respect to bounced emails. Regarding Mail HELO, I see this: *: psapi.net I did edit that file as: *: lionsgatecreative.com But, the changes were later overwritten back as *: psapi.net

Well progress is progress!! So this makes me wonder what the PTR is set to. What is the output of the following (assuming you have 1 IP or that you haven't set a specific IP for mail) host

May 08, 2020 21:31

Hmmm, interesting. Result for root dedicated IP (and each domain resides with dedicated IP): 234.99.9.72.in-addr.arpa domain name pointer psapi.net.

So at some point I'd assume based on this you had this IP assigned to that domain and had a PTR added. This should either be changed to the hostname or if in the case of "send mail from account's dedicated IP" (a setting in WHM>>Server Configuration>>Exim Configuration Manager) the domain name it's assigned to.

Thanks! But, where do you make the changes? I did just enable "Send mail from account's dedicated IP" as it seemed like a good idea.

Most of the time you can't make these yourself (even with root access) - most providers don't delegate this to their users so you'd need to contact them to update it.
