Exim4 - current spam setup

[moseley@hank.org]

Ok, I'll try another exim4 post:

I'm moving to exim4 and SA 2.60 on Woody:

1) Are there common or suggested settings to make in local.cf?

2) What RBL entries (dnslists) are you using in Exim4's ACL list?

3) Any opinions on using a sender callout feature?  Will good mail get 
blocked?

4) Any comments or suggestions on updating a live woody (exim3) system
to exim4?  exim4-config conflicts with exim which makes it a tiny bit
more work to get the config setup (I'll create an exim4.conf file from
another machine before upgrading to hopefully limit downtime).

Thanks,
