[exim] deleting hints database

Hello,

I read in the manual that if I change retry rules, I may need to
delete hints database. I believe I do because:

2008-03-05 13:19:53 1JWjHD-0009pn-MG failed to expand "yahoo\.$\N"
while checking a list: $ not followed by letter, digit, or {

This stems from an error I made realier but I restarted exim and the
same error still appears for some of the mail in queue.

Is the hints database /var/spool/exim/db/retry ?

If it matters, I use FreeBSD 6.3-RELEASE-p1. Thanks!
