[Exim] small discrepancy in config possibilities

hello,

i recognized that the

sender_verify_hosts

option in exim-3,32 doesn't allow the mixture of single arguments and lookups:

if i configure:

sender_verify_hosts = \
!domaine.example:!domaine2.example:!dbm;/etc/exim/domaines.db

the option is simply ignored by exim. whereas:

sender_verify_hosts = !dbm;/etc/exim/domains.db

works well and excludes the dbm mentioned domaines from verification.

wouldn't this discrepancy need a fixup ?
