Just for the record

As noted above, some weeks ago I did upgrade to SOGo 2.0.1 by following the advice in the wiki
http://wiki.contribs.org/Sogo#UpgradeIn the meantime, SOGo has reached version 2.0.2a (which fixes some annoying bugs initially present in the 2.x release).
Unfortunately, after this inital upgrade to 2.x, any subsequent execution of
yum update --disablerepo=* --enablerepo=sogo
would always return a "No Packages marked for Update" message
(on this particular server).By looking at the official SOGo repository
http://inverse.ca/downloads/SOGo/RHEL5/i386/RPMS/ I found that Inverse keeps several versions of SOGo in the same repository folder. In order to get the latest version of SOGo and its dependencies installed on SME,
one has I had to clear the yum cache for the sogo repo first:
yum clean all --disablerepo=* --enablerepo=sogo
yum makecache --disablerepo=* --enablerepo=sogo
yum update --disablerepo=* --enablerepo=sogo
# signal-event sogo-modify
/etc/rc7.d/S85sogod restart
Maybe this information could be added to the wiki entry for SOGo upgrades, if the issue is experienced by others as well? (sorry, I'm not on the wiki team myself...)
