in order to look inside the directory, exim will need '+x' permission.

Having said that:

I think it was able to locate the file and start to run it (13 is "sigpipe",
use "kill -l" for a list; it means that the other end closed the pipe before
the sending end was ready). Maybe the program itself terminated prematurely?
Do you have any logging from this perl script? Can you replace it with

    #!/bin/sh
    cat >>/tmp/mylog

and see what happens? Actually,

    #!/bin/sh
    id >>/tmp/mylog

would be a useful test, it should record both the uid and gid which the
script is run as, so you can work out which permissions are wrong exactly.

My guess is that the perl script is trying to open a file, doesn't have
permissions, and fails. If the above test shows that it is being run as a
group you don't expect, then you could try adding 'group = exim' to the
system_aliases: director.
