I upgraded my server from from 4.5.10 to 5.0 OSS GA. The server is running CentOS4.

After the upgrade, my mail stopped being delivered to my server.

I finally found that sendmail was running...which it should not be correct? I stopped the service, then used chkconfig to make sure it was off for all run levels. Restarted Zimbra....same problem. I finally found out that every time I restart Zimbra services, sendmail is getting started as well. Is this correct?

If I stop it manually while Zimbra is running....it eventually is restarting itself.

Can I safely uninstall sendmail? Anyone else running CentOS4 and finding this problem? This server worked great until the upgrade....and now sendmail is being a real PITA.
