Hi,
I've recently joined a project supporting & developing a web-based email
system which uses Cyrus (1.5.19) as the mail server. We currently have
nearly 100,000 accounts (not all of them active) - Cyrus is rapidly becoming
the bottleneck on the system. We would like to expand to support 500,000
accounts, maybe even a million eventually.
Does anyone have any experience of supporting systems with these kinds of
numbers? Is Cyrus appropriate for these volumes? How can we build in
redundancy (i.e. keeping the system up even if the box goes down)?
Also, some of my colleagues have suggested moving to Courier instead as they
think this would give advantages in performance. However there would be a
big hit involved while we migrated. Does anyone have hands-on knowledge of
both Cyrus and Courier, and could offer any insight?
Thanks,
Barbara
