No yet. SOGo provides debian packages: sogo.nu/english/support/faq/ ... ebian.html
I think you also need some packages from unmaintained, for example:
echo "deb http://inverse.ca/debian wheezy wheezy" >>/etc/apt/sources.list
ucr set repository/online/unmaintained='yes'
apt-key adv --keyserver keys.gnupg.net --recv-key 0x810273C4
And the documentation says port 20000 must be open, this can be done in the following way:
ucr set security/packetfilter/package/sogo/tcp/20000/all=ACCEPT
The SOGo documentation then refers to the config file /etc/sogo/sogo.conf.
