I’ve got bad rating of my sent e-mails because of my invalid Helo.
I have no idea how to fix it.
Ok, I’ve done something and it helps.
I’ve made change here /etc/hostname with my new hostname: development.mydomain.com and added next A records with this domain pointing to my serv. IP .
I’ve changed server hostname in Plesk settings as well and after this last step my e-mail got correct ‘Helo’.
But I didn’t change anything in my Kimsufi panel and he still showing my old hostname… .
Thank you 🙂
This happens because your host has a name that somewhat resembles an IP address, for instance
To fix the problem, you need to do two things:
- Give your host a proper hostname, which is a fully qualified domain name. For instance,
mail.example.com. Note that it must not be a “naked domain”. On CentOS 7, edit
/etc/hostnameand then reboot.
- Add a forward DNS record (A record) for your chosen hostname to your DNS records. You do this with whoever is handling the DNS for your domain.
- Change your reverse DNS to match that hostname; you can do this in Kimsufi’s management interface.
