Does anybody have any advice or opinions about which of these two packages would be better for a large installation. I'd prefer if the package could tie into MySQL for user authentication, and all mailboxes will be virtual in the sense that they won't have local system accounts.
I've read on numerous occasions that Cyrus-Imapd will scale better than Dovecot. I have have not, however, read any hard numbers comparing performance between the two. Yeah, that was useless. :)
I love Dovecot because it's incredibly easy to setup and maintain. I personally haven't had to roll it out to large sites yet, so I've stuck with it. Also, it's been handling email boxes with several hundred megabytes of email with ease. A lot of that great performance is coming from the Maildir setup I use, I'm sure.
Anyway, either one of them might work for you. It really depends on how the system would be used, the type of hardware it's going to be installed on, etc. I suggest you try out both - for 10,000 users, you'll HAVE to do a lot of testing anyway.
