How to send email from not existing mail domain?

1

Hello,

I have VPS server with development sites.
For these sites, I don’t want to set up email domain and mailbox.
I want to send emails from: [email protected] to [email protected] without opening some.server.com mail domain and [email protected] mailbox.
And getting error:
temporarily rejected RCPT <[email protected]>: Could not complete sender verify

Exim config is default after fresh installation.
How can I send email?

2024-05-23 17:44:51 remote host address is the local host: some.server.com (while verifying <[email protected]> from host server.com (some.server.com) [127.0.0.1])
2024-05-23 17:44:51 H=server.com (some.server.com) [127.0.0.1] sender verify defer for <[email protected]>: remote host address is the local host
2024-05-23 17:44:51 H=server.com (some.server.com) [127.0.0.1] X=TLS1.3:ECDHE_SECP256R1__RSA_PSS_RSAE_SHA256__AES_128_GCM:128 CV=no SNI=127.0.0.1 F=<[email protected]> temporarily rejected RCPT <[email protected]>: Could not complete sender verify

Why would you want to send emails without setup email domain? It doesn’t make sense. Do you own those domains?

So, I will not need to set up emails for development sites.

There’s no development staging in email workflow (as far as i know). Email needs to be setup with the standard and protocols from day one.
