Alexis,
I'd suggest qmail-ldap as it lets you use your current user database
almost without modification. qmail-ldap started as a compatible re-
placement for a Netscrape Messaging server. It is used in numerous
large email sites and of production qualitiy. In fact even MP3.com
uses it on their mail servers.
