[Exim] Policy controls for local input

Hello.


Section 42.9 states:

No policy checking is done for BSMTP input. That is, no ACL is run at anytime. In this respect it is like non-SMTP local
input.

Section 5.3, on -bm option, does not say anything about ACLs at all.

This leads to conclusion that ACL are never run for local input.


Section 7.2, hovewer, contains the following:

accept hosts = :

This ACL statement accepts the recipient if the sending host matches the list. But what does that strange list mean? It
doesn't actually contain any host names or IP addresses. The presence of the colon puts an empty item in the list; Exim
matches this only if the incoming message didn't come from a remote host. The colon is important. Without it, the list
itself is empty, and can never match anything.


This needs to be clarified. It seems that Exim does not run ACLs on local input. Why is it so?
