H-Sphere uses the standard qmail configuration. To rebuild it, please follow the steps outlined below.

1. Configure account/group IDs to be used by H-Sphere qmail:

   For FreeBSD:

   # /usr/sbin/pw groupadd -g 401 -n nofiles
   # /usr/sbin/pw groupadd -g 400 -n qmail
   # /usr/sbin/pw useradd -u 400 -n alias -g nofiles -d /hsphere/local/var/qmail/alias
   # /usr/sbin/pw useradd -u 401 -n qmaild -g nofiles -d /hsphere/local/var/qmail
   # /usr/sbin/pw useradd -u 402 -n qmaill -g nofiles -d /hsphere/local/var/qmail
   # /usr/sbin/pw useradd -u 403 -n qmailp -g nofiles -d /hsphere/local/var/qmail
   # /usr/sbin/pw useradd -u 404 -n qmailq -g qmail -d /hsphere/local/var/qmail

   For Linux:

   # /usr/sbin/groupadd -g 401 -r nofiles
   # /usr/sbin/groupadd -g 400 -r qmail
   # /usr/sbin/adduser -u 400 -r -g nofiles -d /hsphere/local/var/qmail/alias alias
   # /usr/sbin/adduser -u 401 -r -g nofiles -d /hsphere/local/var/qmail qmaild
   # /usr/sbin/adduser -u 402 -r -g nofiles -d /hsphere/local/var/qmail qmaill
   # /usr/sbin/adduser -u 403 -r -g nofiles -d /hsphere/local/var/qmail qmailp
   # /usr/sbin/adduser -u 404 -r -g qmail -d /hsphere/local/var/qmail qmailq
   # /usr/sbin/adduser -u 405 -r -g qmail -d /hsphere/local/var/qmail qmailr
   # /usr/sbin/adduser -u 406 -r -g qmail -d /hsphere/local/var/qmail qmails

2. In the /root/sources directory with qmail sources and the qmail-smtpd.patch file (download qmail-smtpd.patch here), execute the following commands, or create and run the script with these commands, under root:

   # cd /root/sources/
   # tar xzf ${QMAIL_NAME}.tar.gz -C ${BUILD_DIR}
   # cd ${BUILD_DIR}/${QMAIL_NAME}
   # patch -p0 < /root/sources/qmail-smtpd.patch || exit 1
   # echo Making
   # make setup check || exit 1
   # echo Config-fast
   # ./config-fast ${MAILDOMAIN_COM} || exit 1
   # [ -d /hsphere/local/var ] || mkdir -p /hsphere/local/var
   # rm -f /hsphere/local/var/qmail
   # mkdir -p /hsphere/local/var
   # ln -s /var/qmail /hsphere/local/var/qmail
   # cp -f /hsphere/local/var/qmail/boot/home /hsphere/local/var/qmail/rc

   Here,
   - QMAIL_NAME is the qmail package name;
   - BUILD_DIR is the qmail build directory;
   - MAILDOMAIN_COM is the mail server domain name.
