Hi Chris,
I remember that article, I think I saw it on PlanetMySQL.com -- but I
can't find it either. I do remember that it encrypted the column
putting it into the database, and used a VIEW to decode it, and then
limited the access to the view.
Hope that helps!

Databases are not e-mail handlers, so the basic answer is no.
However, it's possible to have the e-mail handlers update a database

Hi Philip, thanks for the reply.
Single master + many read only slaves would only solve the problem of
handling many many concurrent read accesses, by distributing the load
across all slaves.
However, I guess the real problem, is that the writes would still need

Your subject is misleading, I would rather call this something like
Chained Replication. Unless your slaves all replicate from 'Master', in
that case your drawing is the culprit. :)

The process is working between Master, Slave1 and Slave2 but
for some reason Slave2 is not writing bin-log information.
So Slave3 is sitting empty and not getting any data because of no data
