It's first-level domain of mine.
I'm using aapanel on my server. All things working normal but I can't install mail server correctly. I have added my steps in to attachments.
Any solution about this problem ?
Thanks a lot
check with nameservers
JAY Nameservers correct. I'm using Cloudflare
a record need fill in a domain name like mail.yourdomain.com
Can you please Check your domain A record and NS here >> https://www.dnswatch.info/
Also are you using NS or A record on your domain registrar to point it to the server ??
The only thing i can think of is either you are trying to have email services on subdomain or your DNS in server is conflicting check wether the IP you supplied is the same as server IP also crosscheck your DNS zone with the DNS manager in the aapanel with your CloudFlare one.
aaPanel_Jose Omg that is work. I have entered first-level domain name in first box and I wrote mail.mydomain.com to second box. That is work. Thank you so much!
