Do you mean a message ID in the sense of ``value of the
Message-ID: header'' (something like <12345@???>)
or ``the ID which exim uses for identification of the
messages on its queue'' (something like 1EGRzl-0003nQ-00)?
I can't see any reason why your configuration would change
the former, but the latter is assigned uniquely by Exim at
message accept time (see src/accept.c, search for ``Now
build the unique message id''). You *could* override it
there from a value supplied in the message headers by
altering the source code, but this sounds like a terrible
idea to me. Do your logs not contain sufficient
information to identify the post-amavis ID from the
pre-amavis ID? If not, can you make amavis or some other
bit of the apparatus log both pre- and post- IDs (perhaps
by parsing the DATA response amavis gets from exim at SMTP
time)?

By the way, this:

is nonsense (well, you might have read that it's true, but
it isn't).
