We do use dbmail here. From what we have experienced dbmail works great. The project is constantly moving forward, and they have a very responsive devel team that is on their mailing list. Their are a few limitations: To do SSL with IMAP and POP3 you need to use stunnel right now. Native support for SSL is on the drawing board but has not been finalized. It does take a little beefy hardware to run the whole thing efficiently. I guess this really depends on how many concurrent connections you have. With us, we have a couple hundred people checking their mail per second. This means a lot of memory usage, since each user has at least a dbmail process, and a mysql process dedicated to them. There are some advantages though: Very easy to write admin tools for your email system, everything is stored in MySQL or PostgreSQL. Webmail is very fast; direct db access. Performance is excellent. Very stable, I don't think I have seen a crash in dbmail since I started testing it a couple years ago. Easy to backup. Very easy to scale up. Just add a high powered db backend, and clustered frontends and you are set to scale to almost any capability. Separate authentication scheme. The user database can be used for other SQL based authentication systems. For example, we use the user database of DBMail for our radius authentication. It is available for debian. :-) -- Bret Baptist Systems and Technical Support Specialist bbaptist at iexposure.com Internet Exposure, Inc. http://www.iexposure.com (612)676-1946 x17 Web Development-Web Marketing-ISP Services ------------------------------------------ Today is the tomorrow you worried about yesterday. _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota Help beta test TCLUG's potential new home: http://plone.mn-linux.org Got pictures for TCLUG?
