Hi. Cannot send mails from Squirrelmail to Gmail (i can send to Yahoo) but not Gmail Can u help me? My server: ubuntu 14.04 using posfix Error : Message not sent. Server replied:Requested action not taken: mailbox unavailable 550 5.1.1 <>: Recipient address rejected: User unknown in virtual mailbox table
The error means that the mailbox that you send the email to does not exist. But the message does not look as if it comes from gmail, check the recipient address for typos. Or you added the gmail domain as local domain on your server.
The Gmail maiilbox is real, exists. It's my brother's. It is correct. How do i verify if i added Gmail as local domain on my server? Thx so much!!!
