I wanted to test zimbra on centos 6 (I'm new to centos). While installing zimbra it said there was a conflict on port 25. So I found out that postfix is the default mta on centos. I then did sudo yum remove postfix and followed the prompts for removing it, but in doing so it removed chrome that I had installed and several other packages that seem to be important. Some of these were cron, some lsb packages, and some others. Why does removing postfix remove these others. cron and the others are dependent on having postfix? Seems odd if they are.
Thanks,

They are dependent on having a local SMTP server, for example cron requires one to send email containing the stderr output of (presumably failed) jobs. If the zimbra packages declare the appropriate provides, you should be able to re-install cron et al. after installing zimbra.

I see that from the previous email. I have been reinstalling them and then checking to see how to keep postfix from starting. After installing cronie, etc. back, postfix was installed. I did postfix stop, but it said it was not running. I'll have to look in the start up and see if it is set to start on reboot.
