Assumpte: [exim] ACL syntax question
Hello,

Odd question - is there any difference between the following 2 ACL
statements:

     hosts = ! +local_domains
   ! hosts = +local_domains


I'm assuming there is no difference.

Secondly, using a named ACL is there a difference between:

      acl = ! some_other_acl
    ! acl = some_other_acl


We currently don't use named ACL's but am about to do so. As far as I
can tell (read) the 'some_other_acl' acts like any other ACL and returns
'accept' or 'deny'. As such a '!' will just negate that answer, so the
above 2 statements are again the same. Correct?



Thanks,

John.
