--- Comment #1 from Graeme Fowler <graeme@???> 2007-10-05 09:36:22 ---
A "deny" in the quit or not_quit acl is superfluous - at this point, the remote
server has either closed the connection gracefully (ie. sent a QUIT) or has
terminated unexpectedly, perhaps due to a network problem or (in the case of
Exim) by dropping the connection on purpose.

This is why the log message says:

ACL for not-QUIT returned ERROR: "deny" is not allowed in a QUIT or not-QUIT
ACL

This is documented here:

http://www.exim.org/exim-html-current/doc/html/spec_html/ch40.html#SECTQUITACL

The ACL for the SMTP QUIT command is anomalous, in that the outcome of the ACL
does not affect the response code to QUIT, which is always 221. Thus, the ACL
does not in fact control any access. For this reason, the only verbs that are
permitted are accept and warn.

and here:

http://www.exim.org/exim-html-current/doc/html/spec_html/ch40.html#SECTNOTQUITACL

Like the QUIT ACL, this ACL is provided to make it possible to do customized
logging or to gather statistics, and its outcome is ignored. The delay modifier
is forbidden in this ACL, and the only permitted verbs are accept and warn.

The fact that you're calling a nested ACL is not relevant - the outcome is a
"deny", which is an invalid verb for the "parent" ACL.

Closing, not a bug.
