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@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

Ok, more information. I have Openwebmail 2.52. I tried to install 2.53 with yum, and get the following. This points to what the conflict is about. But I still don't know how to fix this.
