ClamAv has had RAR capabilities since verion 0.90.
Now, from what I remember Fedora does not include libunrar (even though it's
free) and I think there version of the rpm uses the --disable-unrar switch as well. Don't remember if you are using fedora or not.

Also you have to have unrar installed for MailScanner to unpack it.
Look in the MailScanner.conf for

MailScanner.conf:Unrar Command = /usr/bin/unrar

And point it to your unrar binary
