I use a single username for a dozen email boxes, and the database is 3.5GB. Though you can trim it by dropping tokens that aren't as accurate, or aren't as frequently used, it could still become big, especially with a lot of users. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I'm using FreeBSD 6.2-RELEASE-p2 with Postfix, Cyrus-SASL2, amavisd-new, clamav and dbmail (only IMAP with stunnel) with a pgsql backend. Hi Oliver, Thanks alot for your reply. I was lost on this one! I would like to switch back to a filesystem based e-mail backend (maybe dovecot) - feels better to me. Furthermore I think that dbmail has no good pgsql support (it has some bugs with IMAP) - maybe you would like to try mysql instead (*hirgs*). I think that I may have to switch back to Mysql then. I heard that PostgreSQL is more scalable than Mysql. But I am not an experienced database user, so, please forgive my little knowledge. Why do you want to switch back to to a filesystem based e-mail backend? I suppose storing emails in a database should be more scalable and flexible in the long run? If you would like I can show you my configuration files and table structures. Of course, I would like to see your configuration files. In fact, I am dying to see it. I am planning my current setup to be used for a long term basis in a production environment for a very large user base. Me and my team are currently just designing and testing it out. It might take some time before we can put this server in production. Since I am very new to database terminology, how scalable is a database in terms of the data storage size. I mean suppose, we have 2 users each with a quota of 1 GB. What will eventually happen if they all used up their quotas. That will be about 20 TB in size!!

Why do you want to switch back to to a filesystem based e-mail backend? I suppose storing emails in a database should be more scalable and flexible in the long run? Since I'm the only active user of my dbmail setup it's too oversized for this purpose. I think I can live with a small filesystem based postfix setup, too. Of course it will be more flexible in the long run but I have only a 1,2ghz machine as my main mailserver - simply it is too slow.

I never thought about thousands of user - I never thought about to have more than 10 user. Hehe. Well, if you will have such a huge load Postgres would be the best choice for you.
