stuck at Starting Sendmail when boot

[Weizhong]

hi,

I know this has nothing to do with the Redhat 6.0 I just installed, but with
hosts or server config.

PPP connection, no network.  Before I added a connection, there is
nothing wrong when boot.  After that,  <which works fine>, it takes about 4
mins to pass that step.

I believe it's a configure problem.  Please help me.

Thanks,

Weizhong
