yum list installed evolution*
evolution.i386 2.2.2-7 installed
evolution-data-server.i386 1.2.2-3 installed <<<it's close, are you sure it's 2.2.3
evolution-webcal.i386 2.2.0-1 installed
And that is an afirmative.
I'm using evol e-mail and have had no problems.
The data server is running but I don't think it is doing anything important.
