I have installed iRedMail without problems. I can’t send and recieve mails.

My DNS configuration is:
http://viewdns.info/dnsreport/?domain=wameo.pl

When trying to send a mail from gmail:

Delivery to the following recipient failed permanently:

 kontakt@wameo.pl

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain wameo.pl by aspmx.l.google.com. [2607:f8b0:4003:c08::1a].

The error that the other server returned was:
550-5.1.1 The email account that you tried to reach does not exist. Please try
550-5.1.1 double-checking the recipient’s email address for typos or
550-5.1.1 unnecessary spaces. Learn more at
