When I tried to send mails via rouncube, I got the following error message:


There was an error sending your message: Failed to add recipient: [SMTP: Invalid response code received from server (code: 451, response: Temporary local problem – please try later)]


This happens only in roundcube.

How to fix this issue: If you have access on shell open the /etc/localdomains with your favorite text editor then include the domain name having that error and save.
