Issue User unknown in virtual mailbox table

[Steven S.]

Hi Pleskians!

I recently ordered a Reseller hosting for some of my clients.
I have created a domain and a email address, but whenever I try to send an email, I get the following error message:

SMTP Error (550): Failed to add recipient "user@domain.com" (5.1.1 <user@domain.com>: Recipient address rejected: User unknown in virtual mailbox table).

If u need more info, please advice.
Thanks in advance!
