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.  :-)
