It seems Openwebmail is using Perl-Compress-Zlib from rpmforce, but in Centos this is obsoleted by Perl-IO-Compress, and there is a conflict. This I got when I tried to install the rpmforce package: [root at mail log]# yum install perl-Compress-Zlib Loaded plugins: fastestmirror, installonlyn Loading mirror speeds from cached hostfile * addons: ftp.funet.fi * base: ftp.funet.fi * extras: ftp.funet.fi * rpmforge: wftp.tu-chemnitz.de * updates: ftp.funet.fi Setting up Install Process Package perl-Compress-Zlib is obsoleted by perl-IO-Compress, trying to install perl-IO-Compress-2.030-2.el5.rf.noarch instead Package perl-IO-Compress-2.030-2.el5.rf.noarch already installed and latest version Nothing to do - Jussi On 12.10.2010 9.38, Jussi Hirvi wrote: > Ok, more information.
