Warning.... there a lot of stuff that is pre-internet
in the guts (i.e.
was designed during the Arpanet) so IP support got added to it. And
even with the last versions, its missing a lot (i.e. I'm the person that
hacked^h^h^h^h^h^hadded the original BSD resolv client code to it one
weekend, lord knows how many years ago). Again this is why QMAIL
became the replacement. Borstien is an amazing coder and I respect him
immensely, although his personality leaves a little to be desired...
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?
Ahem ... We did it before they did (by a number of
year actually).
It was also the mail for CS-NET/PhoneNET, when BBN picked it up.
I'm sorry, I was not meaning to imply anything other than my ignorance
of MMDF history.
Mail-11 is DEC's mail standard. And is mostly a
protocol spec.
ACK
PMDF was a pseudo open source rewrite of MMDF (from on
the mid western
universities I believe), that got taken closed and I never knew all of
the politics. Larry M correct me here, he might know some of it, as I'm
thinking PMDF came out of Wisconsin originally. Whoever wrote it, took
the CS-Net C MMDF implementation and rewrote it into Pascal for VMS -
this was during the height the C vs Pascal war in CS Depts and also the
time of the UNIX vs VMS wars. The DEC Pascal Compiler was very good
and was an excellent teaching compiler. Paul W might remember the
ordering of the releases from the compiler group, but I think VMS Pascal
was released before VAX-11C -- which I think played into the MMDF/PMDF
thing. As I recall, VMS Pascal definitely was bundled in the
University package and was 'cheaper' if you were willing to run VMS
instead of Unix at your University. Anyway, the folks that did
PMDF formed a small firm and sold it for a while. There was a
commercial IP implementation from France call TUV for VMS and IIRC, the
TUV folks bought PMDF and whole thing got sold to a lot people and had
quite a ride .
Interesting.
I know nothing about that. I wonder of the Pascal
version got
reimplemented in Java at some point. I do not know. That would not
surprise me.
"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
Microsystems"
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.
That would sound more like it. Also left and right
hands not talking
to each other. Sun had become a large place by that point.
ACK
Sure, but its more work than I want to mess with
these days. Best
wishes and have at it 😘
Fair enough.
Thank you for the history on MMDF / PMDF. #larningIsFun
