Iam using keyhelp , installed on debain 12 , the scenario as following
1- Hostname server.domain.com
2- first domain (domain.com) the domain of hostname
3- Second domain (domain2.com)
After creation and moving backup from cpanel to keyhelp manual , all work good , websites , and emails moved correctly no problem
now when i try to add email example (info@domain.com) it added correctly and choose it own ssl 993 & 465 port without no issue but when i try to add info@domain2.com it give me error (cann't connect to incomming mail server) when i try to change ports ssl or starttls it give me certificate error it pull hostname certificate.
- tried to certbot the second domain to make it wildcard certificate No chance
Tried to add mail cname to the domain2 (mail.domain2.com cname domain2.com) no chance
tried to change Main domain for connecting email clients Use the associated domain name No chance
Any help or ideas to make the second domain work on its mail server or domain.com mail server without issue ?
Thanks
