Topic: Recipient address rejected: User unknown in virtual mailbox table

Hello, I have a bizarre problem, I can send emails from iredmail smoothly.
I can receive emails from gmail, yahoo, hotmail, exim, qmail without problems BUT if I send a mail from another postfix, I get the following error

An error occurred while sending mail. The mail server responded:  5.1.1 <user@domain.tld>: Recipient address rejected: User unknown in virtual mailbox table. Please check the message recipient user@domain.tld and try again

Any ideas?

Post both main.cf HERE should be better.

Your postfix config is not SAME as iRedMail, you should post your questions to postfix mail list instead of asking here.
