"Policiy Control"
http://docs.exim.org/current/spec_html/ch03.html
(see.. still not short enough)

Further, ACLs are processed in order for SMTP as follows (sorta - I
missed a few, didn't stick in loops etc etc etc):
acl_smtp_connect
acl_smtp_helo
acl_smtp_auth
acl_smtp_mail
acl_smtp_rcpt
acl_smtp_predata
acl_smtp_data
acl_smtp_notquit
acl_smtp_quit

When an ACL hits a accept, deny, or drop and the conditions are met,
that is the end of processing for that ACL. warn allows further
processing. require passes to the next one if all its conditions are
satisfied. endpass changes the behavior of accept and is apparently
really confusing.

There are also a few things you can do that trigger a verify run through
the routers, but they don't finish the ACL on their own, they are used
as conditions.

This depends on what ACL it is.
