Let's see here -- "sendmail" is looking for a full-blown DBMS with
transaction & logging capability -- seems to me IMAGE comes to mind... ;)

Let me pose a big "why not?" here -- after all:

  -- the DBMS is native to the platform, thus less dependancy on
another "rough-fit" application [DBMS]
  -- we already know how to program for this DBMS [and quite well, I might
add :) ]
  -- the "port" is to this platform, not the other way around -- I would
maintain that a platform-specific version of a program should make the most
of the resources available to that platform.
  -- I don't think the "structure" of the database will change [except
perhaps with the next release of sendmail, but that would be "another port"
anyway...] however capacity sizing might be an issue [but we have HP & 3rd
party tools for that anyway...]

Of course, one "why not?" reason/rationalization might be that it would
take a significant amount of effort to code the database calls "correctly"
(efficiently?) in the first place...

Just a thought...
