bounces not always come from <> sender, but you can try to reject
as much as possible (i have some acl's in
http://www.ols.es/exim/acl/
which work well at detecting bounces)

this only affects outgoing connections, you can use something like
this:
smtp_accept_max = 120
smtp_accept_max_per_host = 3
smtp_accept_queue = 100
queue_only_load = 2
and
smtp_load_reserve
smtp_accept_reserve
smtp_reserve_hosts
if you have a list of good host, and also some acl's to fine
tune incoming connections:
acl_connect:
accept hosts = :
# Too busy (all hosts)
defer condition = ${if >{$load_average}{10000}}
message = Too busy now, please try latter
log_message = Too busy now ($load_average any)
acl_check_mail:
# Too busy (non-authenticated users)
defer condition = ${if >{$load_average}{6000}}
!authenticated = *
message = Too busy now, please try latter
log_message = Too busy now ($load_average)
