I have a mail server that supports approximately 50-60 radio stations across the country with approximately 700 end users. Because of the dispersant number of users and geographic locations, I have set up a certain number of users at the main office to use Webmin to add accounts to the mail server. NOBODY is allowed shell access to the box but me, and the Webmin limits these people's access to the add user applet.
Despite using system accounts which Aleksandar thinks is unscalable, this setup works perfectly. As new radio stations come online, we create a simple text file and accounts are created in batch. As each account is crated, their mail box is set up.
Right now, I use teapop on that server, but am seriously considering converting that to Dovecot. The load on my server from that many user accounts is minimal.
I went from 4 accounts to close to 700 accounts in under a year. I expect approximately 2k-3k by by the end of the year. Scalability of Linux in general is fantastic, I am not sure how much more I need. Without Cyrus, I am scaling quite nicely and the system is stable. You are right, Aleksandar is making much more out of this issue than is warranted.
