When I try to install Zimbra on a Version 5 Red Hat Server, I get to the point where the installation searches for program prerequisites. Every program is found, except for Fetchmail. When I then go onto install fetchmail, every version that I find seems to have a problem with my server, and the installation does not go through. I was wondering if someone could provide me with either a working fetchmail link, for Linux 5, or an alternative Zimbra installation which does not require fetchmail in the manner that it does now. I have installed a different version of Zimbra on a different server, and I didn't have a problem with it before.
