Hello Admins,

I have at hand a task to setup Dovecot (2.4.1) to handle about 10,000 mailboxes using IMAP/POP3. It's a migration from another system. The current total storage for the mailboxes is 350GB.

I believe several Mail admins are managing such systems, and bigger. What do you recommend as the baseline for the optimization Dovecot engine itself? Assuming the storage is on SSD, is there something you recommend I add to the dovecot.configuration for fast access? Indexing? Anything else? How about the system specs - CPU/RAM?

Thank you in advance.
