redirect dont work, if url contains https

Hi,
my situation is this:
hostname: server.domain.com

Created user with domain: domain.com

i set it to redirect "all domains" to https://server.domain.com:2083
but it works only for http not for https:

e.g. if i enter: http://domain.com then it redirects me to:
https://domain.com/cgi-sys/defaultwebpage.cgi

how can i solve this.

and second problem is.
if i try to create a subdomain:

webmail.domain.com,

i get the error:
A DNS entry for the domain, “webmail.domain.com”, already exists,
but it does not ??

thank you
