Removing exim-4.69-15_cpanel_maildir ?

[excessnet]

Hello,

I'm trying to upgrade my VPS from CentOS 4 to CentOS 5, I'm getting this error

Transaction Check Error: file /etc/aliases from install of setup-2.5.58-1.el5 conflicts with file from package exim-4.69-15_cpanel_maildir
Error: /usr/share/vzyum/bin/yum failed, exitcode=1

So, I'm wondering if I could just remove exim-4.69-15_cpanel_maildir, upgrade, then run upcp --force to re-install everything ? Will mailbox be erased ?

It will also remove fletchmail at the same time, I guess by the time of the upgrade, no mail will be working ?

If you have other idea, I'm in...

ok, it's working, just shutdown the mail server for about 10mins until the update (so I route the port 25 to an other serveur).

I'll do it on the prod serveur soon, so if you see something I didn't, tell me !

Thanks btw !
