I've been looking to replace the above qmail setup with exim/courier, using a mysql backend DB. I considered postfix, but as postfix does home directory lookups on complete email addresses instead of localpart/domain part, and doesn't let you do free-form queries, aliasing domains together looked like it wouldn't be possible without some ugly hack. I'm using http://mail.psknet.com/toaster/ as a starting point for now, and adapting it to meet what I needs. There are some rough web based front ends provided, written in php, but I think these would have to be altered a bit to be useable. The SQL can be a bit complex, but that keeps the database and the rest of the config much simpler and makes it more flexible. You can configure courier to use the same database and tables to find home directories (/home/vmail/domain.com/user/Maildir or wherever) as exim. > Preferly a solution w/ support : WebMail+https, all softwares w/LDAP Exim can be configured to use LDAP backend, but I decided against that as none of the schemas seemed to do quite what I wanted when it came to replacing qmail/vpopmail. > By the way , does anyone know a how-to, or someting else to guide us ??? The above url has a quite rough but fully featured system. A google for "exim pop toaster" has quite a few links, and there are many pages on doing similar things with postfix that can be adapted/expanded. As far as I know, there is no defacto howto/guide for this, however. Regards, Steven

This is very powerful and flexible, and lets you set up virtual domain hosting the way *you* want it. When it comes to GUIs I don't know, but since you can store almost anything in a database, it shouldn't be too difficult to write a simple web frontend yourself. You can have a look at vmail-sql, which really is just a basic exim config with some perl scripts for administration.

I use Courier IMAP myself. I don't really like how it is configured or works, but I guess that's just a matter of taste. When it comes to performance and reliability it seems to work very well. It also supports at least MySQL lookups. tpop3d is a really nice pop3 server, with support for MySQL/PostgreSQL/LDAP account lookups, TLS/SSL, maildirs and much more. http://www.ex-parrot.com/~chris/tpop3d/ -- Erik Grinaker http://erikg.wired-networks.net This signature has been rot13-encrypted twice, reading it is illegal under the terms of the DMCA.

Courier uses standard Maildir storage and has good options for authentication by LDAP and other methods. Cyrus uses it's own method of storing mail which makes it unreasonably difficult to write scripts to manipulate mail that has been delivered. This makes the decision very easy for me, I never consider Cyrus. Someone is about to claim that Cyrus delivers huge performance. I've run 250,000 users per mail store using Maildir format, Courier and Qmail, given a choice I'd do it all the same apart from using Postfix instead of Qmail. The hardware was Dell 2U servers that had 4 U160 SCSI hard drives in a RAID-5 and 4G of RAM which cost about $US10K each. That gave a cost of about $0.04 per mail box at hardware prices of a year ago. If I was setting up a new system now I would use umem cards for external journals of journalled file systems with data-journalling and for the queue. Doing this with one of the 5U Dell servers I expect that I could get decent performance for at least 500,000 ISP mail boxes on a $16,000 system with Maildir. Of course these mail users wouldn't be the cable-modem users who mail .doc files to each other all the time. ;) -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page
