Writing a web gui would also be interesting...

Pretty much every MTA does LDAP lookups these days (i've done it with  
qmail and postfix, and I know people who use exim and sendmail).  
However, it is a lot to learn. MCSEs have trouble picking up win2k  
these days because active directory (ldap) is complicated. SQL is easy,  
most people know it, and it's easy to tie in to a web site (lots of  
books on the subject). Granted, it's harder to scale (that's changing  
now that free relational dbs are getting replication). Then there's  
that redundancy problem (goes with replication).

So, for a single box, simple setup, web interface, not much to learn.  
Go with a simple secure mta (postfix or exim) and a common easy to  
learn db (mysql). That's my 2 cents...
