Avoid using SMTP relay for internal emails

Dear hestiacp comunity,

I have set a mail server for my domain “testmail.com” and also set SMTP relay “brevo” from control panel.
Now when I send mail:
To- [email protected], [email protected]
Cc- [email protected], [email protected]
From- [email protected]

I want that the external receiver get the mail via SMTP relay, but the internal reciver of the same email goes/transfer internally doesn’t use SMTP relay.
Because in SMTP relay sending a mail to multiple receiver count as multiple emails, so if the internal mail deliver locally then only for external receiver I need to use SMTP relay.

Please someone help me if possible.

Thankyou
Chris

Sorry now i realize that hestiacp deliver internal address emails internally by default.
actually i accidently make some changes in template file and remove local deliver option my bad.
