I have updated to the latest ispconfig version. Also before this I updated my CentOS 5.4 OS with yum making sure that postfix is not updated. amavis is now not running. Attempting to start amavis results in the error: error loading required module Compress/Zlib.pm dualvar is only available with the XS version of Scalar::Util ... I have fixed this before but I am having a problem finding that fix. In the mean time I have disabled amavis so that I mail can be delivered. Last time I believe I fixed it by updating CPAN. This has not worked this time. Does anyone out there know of fix?
