+This condition is relevant only in an ACL that is run after a message has been
+received, that is, in an ACL specified by &%acl_smtp_data%& or
+&%acl_not_smtp%&. It checks all header names (not the content) to make sure
+there are no non-ASCII characters, also excluding control characters. The
+allowable characters are decimal ASCII values 33 through 126.
+
+Exim itself will handle headers with non-ASCII characters, but it can cause
+problems for downstream applications, so this option will allow their
+detection and rejection in the DATA ACL's.

JH/03 Bugzilla 1157: support log_selector smtp_confirmation for lmtp.
+TL/04 Add verify = header_names_ascii check to reject email with non-ASCII
+ characters in header names, implemented as a verify condition.
+ Contributed by Michael Fischer v. Mollard.
+
Exim version 4.82
-----------------
actual external source IP:host be used in exim instead of the IP of the
proxy that is connecting to it.
+ 2. New verify option header_names_ascii, which will check to make sure
+ there are no non-ASCII characters in header names. Exim itself handles
+ those non-ASCII characters, but downstream apps may not, so Exim can
+ detect and reject if those characters are present.
+
