This documentation is for Dovecot v2.x, see wiki1 for v1.x documentation.

We run two different clusters of dovecot servers. Both clusters are highly overengineered and can handle the load easily.

This first image shows the current graph of our webmail/dovecot cluster. You can see we do over 5000 simultaneous users. The week before was slightly less due to a local holiday.


The second image shows the number of connections on our direct IMAP cluster. We have over 1000 simultaneous connects on it, even though this service is still experimental and not released widely.
