Most of end-users connect on pop3d (we provide a pop3 optimizer to reduce I/O, see http://www.mail-archive.com/cyrus-de...@lists.andrew.cmu.edu/msg01194.html) , others connect on the webmail (our webmail uses disconnected imapd sessions and is optimized thanks to Cyrus statuscache db). > Also, how many NAS servers/appliances are being used?

Hi, where does Cyrus IMAPd stand today? When I was starting to think about moving to a open source mail system (migrating away from Lotus Domino btw.), there ware Cyrus IMAPd, Courier and UW-IMAP I think. Cyrus was the only "full flavored" IMAP server with active development. We were going the 2.2. path, while 2.3 seemed to "fresh". So there was development. On the other side there were still many people complaining about Cyrus being too complex and too unstable with all the BDB fiddlings. Then dovecot emerged and quickly evolved. I don't know why, but I seemed to become everyone's darling the the favorite IMAP server to many people. It came up with SIEVE and ACLs, which before were more or less a domain of Cyrus. And yet it is still evolving fast, with "easy" replication mechanisms, SIS etc. And still, if someone asks a mailing list (not here certainly) how to start with IMAPd, many people shout, to go with dovecot and not using Cyrus. I don't know, where this bad karma is coming from - I'm still happy with Cyrus. One point may have been from the documentation, that's why I really appreciate the new web site. I hope it will help. But where does Cyrus IMAPd stand today? It may be Murder/Aggregator - but how to get the people, when on first contact, where they just need a simple IMAP server, they are pointed to other product, which they then stay with?

Umm, what? We run Cyrus IMAP server with no Murder for 20K+ people. Murder may be a feature but it's not a deployment requirement. We used Perdition, originally just thrown up to provide a transparent bridge as we migrated from Uwash to Cyrus. But as things moved along, we ended up with Perdition and multiple Cyrus backends and no good reason to switch over to a Murder.

I end up granting myself rights to various users' mailboxes to investigate when we see one of our users sending out spam. It usually turns out that they have been phished recently. Once I grant myself rights to their mailbox, I see the mailbox in my regular email client (Alpine) in the "Other Users" hierarchy. Does this work without Murder? How do you investigate users' mailboxes in cases like this? Andy Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/

Admittedly clunkier but the number of times where I've had to poke directly is small. Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/

In the case of a multi-server setup, it depends on if your murder substatute will show you the folders across back-ends or not in a listing. you can always connect directly to the back-end (bypassing murder or it's replacement) to see all "other users" for that back-end.
