I have recently done so.
The problem with all these database lookups is that Exim's design does not
make it possible to use the database in an efficient manner. Each Exim
process that issues a query has to set up a new connection to the
database, do the lookup, and tear down the connection again. It is not
possible to retain the connection over long periods, nor is it possible
to prepare the query once, and re-use it again and again and again.
