Hum. I have no experience with MMDF. Perhaps I should play.
We shipped it as Masscomp's default Mail System
for a longtime.
I never knew that MMDF was used anywhere other than SCO Unix. (I don't
know which SCO product.)
According to Wikipedia PMDF was used on VMS. Now I wonder if there's
any relation to PMDF and what I've frequently heard referred to a Mail-11.
It was only after I left that they broken down and
switched to sendmail
to be like Sun and much of the rest of the internet.
The Wikipedia article also indicates that PMDF became Sun Java System
Messaging Server. Which seems to counter Clem's comment.
Or, perhaps as typical for Sun, there are multiple solutions to the same
""problem. Ship Sendmail with the base OS but sell a larger product
that (hypothetically) does a super set of functions.
any MTA on the internet had to be hardenned. I'm
sure MMDF could be
attacked with stack overwrites and strcpy(3) style attacks because when
Crocker wrote it, that was not what was being considered.
Thankfully you don't have to put an MTA directly on the internet to be
able to play with it. It's trivial to put an MTA behind a smart host
that that shields the (potentially) vulnerable MTA from the brunt of the
Internet.
