Hello Everybody!

I've the same issue. In my case,I change the hostname by WHM interface and everything stay ok, but when I reboot the server, the problem come back.

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.

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: mailips.png

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?

Regards. #stayhome ♥
