Why Cyrus?

[Paolo Cravero]

My 2 cents...

I agree on this. It took a me a lot of trial-and-error when I tried to replicate in Dovecot our multidomain virtual-user Cyrus setup. Also the use of ACLs to share mailboxes was different and I couldn't converge to an identical behavior.

With 26 TB of messages stored on Cyrus mailstores in individual files, backups can be a nightmare. I really liked the storage bins offered by Dovecot and the automatic archiving to lower-performance disks when I played with it, because it would cut by a factor of 10-100-1000 the number of files to consider.

As I said: my 2 cents.
