Thanks a lot for a clear explanation!
Our firewall is actually on Cisco 1700 series router.
Does anyone know if there is a way to tell Cisco router to deny it
instead of dropping?  This is actually a question to other group,
understand, but maybe someone knows?

I also found that you may tell courier -noidentlookup and am going to
try it too.

It's not so much them needing identd to work, it's more of stupid
firewalls 
that drop identd instead of denying.  Droping doesn't notify the other
side 
that the connection won't happen, so the other side keeps trying and 
eventually times out.  If the packets were denied, a denial message
would be 
sent back, and the other side would quit trying to send such packets,
and go 
on about it's business.

Identd should always be denied instead of dropped.
