Check the Postfix logs. Check your DNS and give DNS time to propagate. 🙂

yes i did what you said
here is my config :
i have mail.domain.com configured properly
then i create a domain2.com and added it to mailcow “add domain” and got the dkim key
in the domain provider i made this setup
SPF : “v=spf1 ip4:<server-ip> _all”
DKIM: dkim._domainkey with the value from mailcow UI
autoconfig CNAME points to mail.domain.com
autodiscover CNAME points to mail.domain.com
domain2.com MX 10 mail.domain.com

I can send emails with the new domain but i cant recieve
