you might want to upgrade that. there are numerous improvements in the
current release 4.14, and 4.20 is in testing but not quite ready for prime
time. i'm pretty sure that there are rpms for 4.14 around.

sort of. it needs to be a specification for how to search the file, as well
as providing the path to the file, e.g.

  data = ${lookup{$local_part}lsearch{/usr/share/local/exim/}}

this specifies that we are to use the local_part of the incoming address to
do a text search (lsearch) of a file in simple alias format. whatever is to
the right of the colon is returned as the data item. if you wanted to use
berkeley db to do the searches (not unreasonable on a Very Large Mail
Server), there is an alternative to lsearch that does that. you could even
get them out of an SQL database like PostgreSQL or MySQL; exim supports
that too (and LDAP, for that matter).

text search or berkely db style is probably more than enough, though.

it should be part of whatever alias file you give a path to. exim imposes
no restriction on number of alias files, i typically run from 1 to 3 per
virtual domain (if majordomo is hosted on the domain, i have two for
majordomo and one for non-majordomo aliases.)

exim -bt is your friend.

   exim -bt

will give you a basic test.

   exim -bt -v

will give you more detail. if it's not enough (usually it is), one of the
-d options can give you enough debugging output to choke a small horse.
