courier-imap Installation Trouble

[spflanze]

I am trying to follow the installation instructions at:
http://isp-control.net/documentation/dok...ion:centos
by SSH on a remote VPS system my ISP host set up for me.

I am at the point of installing Courier-IMAP. I navigated its website to the appropriate downloads for my Centos 5 x86_64 system. This is at:
http://www.thatfleminggent.com/packages/.../repoview/

Pasted below is what happened:

root@server [/etc/yum.repos.d]# rpm -Uvh http://www.thatfleminggent.com/packages

As the above shows I was able to install courier-imap but courier-authlib fails. When I installed courier-imap I did not know I already had a different version of it installed. This is courier-imap-4.6.0-2cp. I also have a version of courier-authlib-0.62.4-2cp installed. I do not have any version of courier-authlib-userdb.

It appears to me that the installation of courier-imap was a mistake because I already had the -0.62.4-2cp version of it. But this must also mean that the version of courier-authlib-userdb should match the others and so should be courier-authlib-userdb-0.62.4-2cp. I cannot find this version anywhere at thatfleminggent.com using the advanced Google search function for it that was confined to that site.

What is going wrong here? Where did these *cp versions that will installed by my ISP come from?

CPanel is already installed. This installation was done by my ISP when the VPS hosting service was set up. I want to migrate from it to ispCP. Does the "cp" in these version names mean it is a version for CPanel?

Should courier-imap-4.7.0-1.el5.mf.x86_64.rpm be removed?

I have yum priorities installed and running. I know it is recommended by some and recommended against by others. So I have not been sure if I should have it running.

Ispcp should be installed on a *clean* system. Ask your provider to give you an unmodified centos base installation with your VPS system instead of one preloaded with cpanel, as I'm quite sure that you will encounter many problems if you just try to go ahead with this cpanel-tampered versions of the base libraries.

I have decided to ask the ISP to switch to Debian. Your instructions for installing on Debian seem much simpler. It also as a large user base where I can get support.

Thanks for your reply.
