I have installed iredmail and set up everything fine, and send some emails from outlook. After send some mails it seems like mails are not gone from outlook. So I tried to send mails from Roundcube and got the below error.

========
SMTP Error (451): Failed to add recipient "xxx@gmail.com" (4.3.5 Server configuration problem).
========

So tried with different mail id like yahoo/gmail/hotmail etc and I got the same error. I tried to add dkim for my second domain in ireadmail using the below link.
