Error SMTP (450). Recipient address rejected: User unknown in virtual mailbox table
08-28-2018, 05:43 PM
Good morning to all,
My problem is the following:
I have two A and B domains configured in my Sentora panel, although the MX record of domain B points to another IP (the mailboxes are in another domain provider)
The domain A that has the full panel (web, dns, mail, etc.) is not able to send emails to mailboxes in domain B.
The error that shows me:
SMTP error (450): It was not possible to establish recipient "david.fernandez@xxx.com" (4.1.1 <david.fernandez@xxx.com>: Recipient address rejected: User unknown in virtual mailbox table).
I understand that I can not send emails because the mailboxes of domain B do not exist in my Sentora panel, but they exist in my other domain provider and apart the MX records point to another server.
How can I fix this so that my domain A can send emails to another domain B with the mailboxes in another site?
I do not know how to solve this ... I need help please!
Thank you very much!
