I'm not sure the following can be used in your situation, but
I had a similar problem with a director config.
My problem was the 'require_files' option: when the expansion did fail,
the driver was run even though this was not the desired thing (the whole
expansion resulted in '', which was not what I expected at first).
So I resolved this in a two-fold search
instead of
require_files = /path/to/som/dir/${lookup {some_string} lsearch {file_to_search} {$value}}/some_other_file
I first checked whether my lookup returned some value, and if not I required the
file to be a non-exitent file, which was what I wanted.
the new condition is:
require_files = ${lookup {some_string} lsearch {file_to_search} \
{/path/to/som/dir/${lookup {some_string} lsearch {file_to_search} {$value}}/some_other_file} \
{/some/file/that/cannot/possibly/exist} }
(syntax not guranteed, but you get the idea)
Maybe you can first check that your banner lookup files exists
and then do the lookup, there is certainly a way to do this.
There can't plausibly be any kind of config you can't do with
exim, could it ?? :-))
