For 1 use something like this.
sender_reject_recipients = *@partial-lsearch;/etc/exim/rejects
sender_host_reject = *@partial-lsearch;/etc/exim/rejects
rejects can be a list of email addresses and hosts this way.
For 3 somthing like the following is needed. (I believe there are plans
to make this an lsearch list as well)
sender_net_reject = "206.185.0.0/255.255.0.0\
:208.1.232.111/255.255.255.0\
:209.14.30.0/255.255.255.0\
:204.176.100.0/255.255.255.0\
:206.149.148.0/255.255.240.0\
:205.177.90.0/255.255.255.0\
:207.33.10.0/255.255.255.0\
:207.33.109.0/255.255.255.0\
:208.16.112.0/255.255.240.0\
:208.1.117.0/255.255.255.0\
:208.9.65.0/255.255.255.0\
"
For 2 you need to use the filter stuff, which I haven't used. I use
procmail instead for historical reasons.
Also, you might want the following in your configure file.
sender_verify
sender_verify_fixup
#sender_verify_log_details
sender_verify_reject
