some thoughts

On startup run acl tests for :
open proxy config
smtp open relay config
CONNECT to port 80 config
and error for the first two, warn for the third.

regex acl's:
We could combine multiple regex acls of the same type with regex '|'
clauses before compiling the regex.. This would make our matching more
efficient. An extension to this would be to combine all the regex acl's
of the same type from _access lines into one large regex and compile
that.
