Hello,

This sounds like an issue that we commonly see on Virtuozzo VPS's where the hostname needs to be added to the container from the host node. You need to let your provider know to update the container name so it stops going back to what they have set for the default.

Hello! @cPanelLauren

Thank you for reply.

I'm using OVH datacenter and my Cpanel is a docker running on Proxmox Environment.
Do you know if this tips applie to the same situation?

Best Regards!

I'd assume so @Fabricio Galdino though I am admittedly not nearly as familiar with that configuration. OVH should be able to assist you with this if you don't have the access to modify it.

Hello @cPanelLauren ,

In v86.0.17

Thats my exim conf:

And I see /etc/mailhelo file x.com has in. And x.com have dedicated ip (ex:192.168.2.1)
192.168.2.1 -> RDNS -> mail.x.com

But when I sent mails HELO going with default hostname. Am I missing something?
