Hello,

I’m having an issue with my Cyberpanel routing email locally instead of using a remote mail exchanger. Any ideas on how to set a domain to use a remote mail exchanger instead? My server uses Postfix (and sendmail I believe).

In Cpanel, this is the setting I would need to change to fix it. I cannot find a similar setting in Cyberpanel.

Basically when websites hosted on the server send an email from a form, it routes it to a local mailbox (if set up on server) instead of the one defined in the domain;s MX records. So I can check mail from web forms through the webmail app on the server, but these specific emiails from the web forms are not going to the correct box hosted elsewhere.

Any ideas?
