[Løst] problem med mail med egen domene

[frustrert gamer]

jeg har en venn som skal sette opp en mail med egent domene. men han har noen problemer med at han kan sende mail fra den, men han kan ikke motta mail, den er liknet til sin hoved mail. dette skrev han ihvertfall til meg

 

I have a problem with my email. Sending mails is working fine, but I can't receive any emails on the accounts I have set up for my domain.

When I send an email from an account ouside my domain to an account in my domain, I get the following error:

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

[email protected]
SMTP error from remote mail server after RCPT TO:<[email protected]>:
host mail.existhost.com [xxx.xx.xx.xx]: 550 sorry, no mailbox here by that name (#5.1.1)

Receiving mail from an another account within the domain is working fine.

What can I do to correct this problem?
