I'm trying to reject incoming mail from a specific sender who has a
mixed-case local part. I use
sender_reject_recipients = partial-dbm;/usr/local/exim/tables/blacklist
which normally works fine. However, mail from that sender arrived last night
despite their address being in the dbm database. After testing exim in debug
mode on a separate port, I think the problem is the mixed case of the local
part. If I add a lowercased version of the address to my blacklist and test
that in an SMTP connection, it's rejected as I expect. However, the mixed
case version is not rejected, even if both the mixed-case and lowercased
versions are in the database.
