Email Forward Accounts "User unknown in virtual mailbox table."
When I create email forwards, it doesn't seem to pass a test, and refuses to let the remote server send the email into the server. I checked the DB, and the accounts are listed in the 'Mail_forwarding' table.
sending from a remote account using thunderbird, I get the message:
An error occurred while sending mail. The mail server responded: 5.1.1 <account@domain>: Recipient address rejected: User unknown in virtual mailbox table. Please check the message recipient account@domain and try again.
I've tried searching a bit, and haven't found any luck finding information on this specific situation.
