I successfully installed iredmail on my ubuntu 16.04 vps. I can log into and send mails from round cube.

The problem is that, I am unable to configure thunderbird as mail client while following this tutorial https://docs.iredmail.org/configure.thunderbird.html
Which configuration should I enter (see attached file)

Also, should I add entries in my DNS for imap.xxxxx and smtp.xxxxx
