At the San Pablo CEU University (Spain), we move to roundcube 0.3 in
september 09, before we
have and old squirrelmail.
Number of users: 15.000+
The server architecture is based on a 2 frontend active-pasive apache2 with
MySQL 5 replication
master-slave and 2 backend, active-pasive with postfix (2.3.3) and dovecot
to a Microsoft AD.
Our students are very happy with the change and its stability. Personally i
am really enthusiastic
with the plugin architecture and hope to see in time, some calendar and task
The plugins the we use are contextmenu and serverinfo, and testing more in
the test enviroment.
Thanks to all people making Roundcube!

> Number of users (max): 70,013
> This is the number of preference sets in the database. We have
> more IMAP accounts, but they have not yet chosen to visit our Roundcube
> Average of concurrent users: 500 to 2000
> The number is highly variable based on time of day and our
> academic calendar.
> A snapshot from this morning shows:
> Active in the last hour: 2715
> Active in the last 5 minutes: 1879
> Active in the last minute: 1096

> Number of hosts serving Roundcube: 19
> We are using round-robin DNS. These machines are separate from
> our IMAP servers and serve Horde/IMP also.
> Database backend software: MySQL 5
> IMAP backend software: Cyrus and ImapProxy
> We use a proxy with unlimited credentials to allow authentication
> to be performed by CoSign (http://weblogin.org/)
> Other webmail software which is offered as alternative:
> We continue to run Horde/IMP mail as we have for many years. Our
> Horde/IMP install has more regular users than our Roundcube. We

> Some interesting, un-shared modifications have been:
> * All folder searching and a new search interface
> * A checkbox column
> * Horde Addressbook read/write
> * Non-scrolling column headers
> * A new skin (still working to make it 3.1 compatible)
> * Forwarding full headers
> * Forced client refresh on upgrade
> * CoSign authentication
> We're working on sharing these changes and more. We've had between 2
> and 5 developers working on RC part time for the last year.
> We would be happy to share more about our experiences with Roundcube if
