I consider myself so advised.
Wait, are you saying that qmail was written as a replacement for PMDF?
Or that you used qmail as your replacement for PMDF?

I'm sorry, I was not meaning to imply anything other than my ignorance
of MMDF history.

"In 1999 PMDF was translated from Pascal to C. The C version of PMDF
became the basis of the Sun Java System Messaging Server of Sun
I wouldn't bet that (the C version of) PMDF was reimplemented in Java
just because the name contained Java. I seem to recall Sun putting Java
in the name of many products at the time.
