This is interesting.  A friend of mine works for a university and he 
told me they did exactly this.  They have a lot of lists .  For 
professors (500+), for other workers (600+), for students (15000+).
They've added lists information in their local LDAP server so
Postfix queries it and handles it just like local aliases.  They did 
this not because they don't like a mailing system but because, at the 
beginning, it seemed easier than integrating Mailman or another manager 
to their solution.

There are some caveats, like not managing bouncing (there are cases when 
the student is not registered anymore and his e-mail account is 
cancelled, but it is still on the list -- it is just an alias --, they 
doesn't seem to have a fully automated solution!), but I can't remember 
of other big problems they had with this approach.

Mailing list managers insert headers and contents to make e-mails match 
with (kind of) recent e-mail rules for mailing lists.  This is specially 
important if you are going to deliver to other SMTP servers.

But since it is an internal solution, you see any other problems with 
the approach of just using Postfix aliases?
