I've been using Cyrus for about 6 years now, the biggest pain was upgrading from 1.x to 2.1, which was fairly complicated, had to test it a half dozen times in vmware before migrating the real deal. Never really had a problem with cyrus that I can recall. I've always stored passwords in LDAP(authenticate via PAM). I've never been fond of the sasl stuff cyrus likes to use, but once it's all disabled and put in plain text mode it's fine. Very fast, I like the acls, on my home mail server I have about 150 accounts, all of which I can subscribe to from my main account, some very basic sieve scripts for filtering spamassasin mails to a central spam folder. I use squirrelmail for my email client, which gives me a convenient little drop down box which I can choose my "from:" address. My latest mail systems are running courier(Maildir) because they have a NFS back-end and Cyrus doesn't play well with NFS last I checked. Certainly on the surface at least courier doesn't seem as powerful as Cyrus, but for basic stuff it seems to work fine. I haven't gone in depth in either Cyrus 2.x (short of basic sieve, everything else is the same stuff I was using in Cyrus 1.x), or Courier, my needs are pretty basic. Mostly have stuck with Cyrus on my own stuff since I've been using it for so long, and haven't had a reason to migrate. The full text index stuff in cyrus sounds cool but it seems you have to do a full re-index(which takes a long time on my system) in order for it to be effective, perhaps there is a way to dynamically update as messages are moved around. I haven't used quotas in cyrus in 5 years, but worked fine at the time. My personal email server(about 4 users including myself, 99% of usage is me) stores about 300k emails, so nothing spectacular. I don't recall ever having data corruption with Cyrus. On paper at least Cyrus looks like a pretty bad ass system, though I don't know if I'll ever want to be supporting an email infrastructure for a large enough site to really take advantage of it(with all of the horizontal scaling it seems to be able to do in the newer versions). My personal servers run debian, I haven't tried cyrus on CentOS. nate
