New to the list, question concerning the automatic update

All,

Yesterday I went out and using the automatic update agent, I installed all
the pending updates to my 7.2 RH system.  I had not run the updater in
awhile, so there was a fairly large number of updates to be had.  Naturally,
I selected them all, and then let the updater do its thing.  It appeared to
complete properly, but I noted that my sendmail was still sitting at 8.11.6,
and doesn't appear to have been updated.  So, I tried to update agent again,
and of course the agent now tells me that my system is current.  Looking
back at the process, I am not sure that the agent completed successfully
after all.

Having said all that, my question is simple...Is there a way to tell the
agent to update once again certain and/or all packages?

Thanks in advance for any assistance or insight anyone might provide...
