It is quite safe and secure enough. The recent audits and paranoia-fit coding sessions Cyrus went through probably have left it with very, very few holes (none known). AFAIK murder requires full conectivity to all servers, since it does referrals. I am not sure if you can tell 2.2.x cyrus to never refer and proxy everything (so you could have the backends fully firewalled), but even if it doesn't, you can use a Perdition proxy to do it. > 5.

You can have different frontends talking to the same set of backend servers. Just make sure the mupdate server is up to the task (as well as connectivity to it). Syncing two *active* cyrus spools is not anywhere close to trivial, so the above method is much simpler to set up. > Currently, we are using an outsourced email hosting provider, and the > speed, because it is all IMAP, and because we deal with a lot of large > attachments, is *very* slow.

With murder, you could even pull the ingenious trick someone posted a while back, of moving the user mailboxes to backends close to their networks, while still having it all accessible everywhere, in a flat namespace (shared folders REALLY benefit from a flat namespace). -- "One disk to rule them all, One disk to find them.
