Downloaded minimal & full to prox2.
Booted DVD, did Fedora style install.
Forgot software type. Just command line at boot.

dnf -y groupinstall "Server with GUI"
dnf -y groupinstall "Development Tools"

mkdir /data
Edited fstab, moved /home to /data
mkdir /home/home; mv /home/ to /home/home/.
Edited passwd for 
rmdir /home; ln -s /data/home /home

 no gui.
At root or  login, startx and GUI is up.
------ perl-Text-Iconv missing for openwebmail -------
# cpanm Text::Iconv
Still not found as installed package
dnf install -y rpmdevtools rpmlint
mkdir /root/tmp
cpanm App::CPANtoRPM
echo "
%packager /usr/bin/rpmbuild
%_topdir /root/tmp
" > ~/.rpmmacros
cpantorpm --install-base /usr Text::Iconv
dnf -y localinstall /root/tmp/RPMS/x86_64/perl-Text-Iconv-1.7-1.el9.x86_64.rpm
Then , it seems, replace /usr/lib64/perl5/vendor_perl/auto/Text/Iconv/Iconv.so
with one gleaned from /root/tmp/RPMS/x86_64/perl-Text-Iconv-1.7-1.el9.x86_64.rpm
rpm2cpio perl-Text-Iconv-1.7-1.el9.x86_64.rpm > /tmp/yy; cd /tmp; cpio -id < yy
Test libs
ldd /usr/lib64/perl5/vendor_perl/auto/Text/Iconv/Iconv.so

Success: have perl-Text-Iconv

Later advised by the Rocky forum:
dnf -y  install epel-release

dnf -y install httpd
systemctl stop firewalld
systemctl disable firewalld
systemctl enable httpd
systemctl start httpd

--------- openWebMail ----------
wget https://openwebmail.org/repo/el9/openwebmail-el9.repo
dnf -y install openwebmail

/usr/local/bin/openwebmail-tool --fix     sets u+s on openwebmail*pl files
