We do primarily SME 'corporate' services, (and R&D) so are *way* below that on
any one server.

Enough so as to be able to afford near-real-time checking - essentially 24x7

But, from curiosity, where do you ID scalability barriers in Dovecot vs Cyrus -
aside from Cyrus obvious longevity/experience advantage?
