When booting Fedora 9 on a laptop the wireless network connection isn't activated until the NetworkManager is up and running. And even then only when the user enters in any passwords.

With no network on bootup, for some reason my sendmail needs a "service sendmail restart" before it will send e-mails.

I'm looking at this from two angles.

1. Does anyone know how to attach a program to run after the network manager makes a connection.
2. Does anyone know where I can look to find out why the messages are getting stuck? I'm assuming sendmail as some type of cache in place, as squid does the same thing.

I've checked the logs and such and nothing useful. Other than domain lookup failed sort of messages. But with no network when it starts that's expected.

Here's the types of errors we get:
