You perhaps think we are adding Perdition to the mix, and assuming we
have a single box that might get overloaded. No, we've had Perdition
running on a load-balanced pool of 4 Linux boxes for about a year and a
half. This was our abstraction to hide the 10+ UW-IMAP servers from the
user population and to ease account migration between mail-stores. I
expect this migration will take some months to complete, and the ability
to hide from the user what mail-store they are on will be essential. I
imagine we'll keep using Perdition I can't see a compelling reason at the
moment to move to a Murder setup. .
I'd recommend switching to nginx from perdition. Although you'll have to
write your own authentication server, that's pretty easy with perl +
Net::Server, and the overhead of nginx with a large number of connections is
a lot smaller than perdition.
