No need to guess. Exim will happily TELL you wot's wot.

A debug run of that acl should tell the tale. At any given moment, anyway.

If the problem is sporadic, as DNS can sometimes be, why not change it to a
'warn' verb, add logwrites and log_message lines to log the relevant info it
had in-hand, sought, and got back. Or not.
