Connect to mail.domain.com throw port 80 (HTTP) HOW TO ???

As SKaero said it sounds like what you need to do is check you webserver config or virtual host file for the site. A port redirect in iptables will not work because http and https are different protocols. You may get help faster if you ask the community for you webserver rather than Roundcube.

I'm not sure how else I can explain it. You need to check your webserver config. Your webserver is something like Apache or IIS. To see if the redirect to HTPS is being done in there somewhere.
