Our office of about 100 users is presently running its mail through an Exchange 5.5 Server. The Exchange server is protected by Linux server pass-through server running Exim4.
We intend to move all of our mail and directory services to open source software, probably Exim4, Dovecot and OpenLDAP.
We have a mixture of mail clients. These include Mac OS9 Entourage (about 30%), OSX Entourage (20%) and Apple Mail (50%). About 30 individuals also look in to their mailboxes using squirrelmail.
Each user is permitted a mailbox of no more than 20MB in size. Project mailboxes may rise to 200MB, however, with up to 5 simultaneous users connection to each project mailbox.
I would be grateful for comments on the suitability of deploying Dovecot in this production environment. I already use Dovecot for a small number of users in a different environment (Mac Eudora, XP Outlook, Squirrelmail) and it appears to work without fault.
