As im using exim on my system with mysql support i normaly compile it with it. the exim ebuild file handles the activation of the Different lookup methods a little bit problematic because it uses a simple sed to replace just the LOOKUP_INCLUDE definition and the LOOKUP_LIBS definition completly with the special db driver. But when its replaced eg by the ldap lookup method, i cant be replaced too with the mysql lookup. But what if u want both. The second problem was that in the mysql part the LOOKUP_INCLUDE part was missing, but it is needed because it else cant find the HEADERS, and in the LOOKUP_LIBS definition there was also included the -lldap which realy has nothing to do in the mysql definition. ( i had to remoce it manualy) Hope this could help make it more bugfree ;)
exim-4.04-r2 should be available on rsync servers within 24 hours. emerge rsync emerge exim USE variables supported now - mta-mysql, mta-pgsql, mta-tls Please install and let me know if this gets you the setup you need.
It seems to work now ;) Great job, the ebuild changes look good ;) (this parts are much better then before)
