Actually, no.  Look at Franz' FTP server (opensource.franz.com) which is
most definitely a package but hardly a library.  Much better would it
have been if Franz wrote an FTP server library and then wrote their FTP
server on top of it.  Then, if I thought they approach on the FTP server
was poor and wanted to do it differently I wouldn't have to implement
the library all over again.

In Lisp the technical difference between application and library is
certainly less clear than in (for example) C but the programmer still
have to think about how others will his software for it to become a good
library.

We use Exim at the moment and /etc/aliases to shovel mail into Mailman.
I think Exim has some features to redirect messages into your software
and then back out again.
