-
- This is configurable in PMDF on a per-channel basis. Options range from
- nosendpost, which generates no postmaster copy no matter what, errsendpost,
- which sends a copy to the postmaster if the regular return address, to
- sendpost, which gives the postmaster an unconditional copy.

-
- Speaking as a Postmaster, let me say that I regard the contents of user
- messages as strictly confidential. I luckily received training in keeping such
- secrets when I was very young since I'm the son of a doctor -- the stuff I knew
- about as a little kid never ceases to amaze me.
-
- PMDF also provides the option to deliver just the headers of messages to the
- Postmaster. This support was incomplete in V4.0 but was considerably enhanced
- in V4.1. I am also considering the addition of support in PMDF for
- sensitivity-based handling in this area now that message sensitivity levels are
- standardized (RFC1327).

-
- I've had at least one case where I inadvertently became aware of certain
- extra-connubial goings-on that clearly were not common knowledge. (I am able to
- mention it now only because this subsequently became very public information --
- in short, something of a scandal.) This happened simply as a result of my
- noticing an unusual pattern of messages being sent between people who otherwise
- would be unlikely to communicate. (In other words, traffic analysis.) Then lo
- and behold a bounce-o-gram dropped in and the subject line, as we say, said it
- all.
-
- I mention this to illustrate two points. First, it doesn't take much to figure
- out who's sleeping with who if you want to know such things. Logs of messages
- sent and received are often more than sufficient deductive ammunition. And
- second, inadvertent knowledge of things is going to leak out no matter what
- precautions are taken.
-
- In the final analysis you're better off having a Postmaster who is aware of his
- or her responsibilities and takes them seriously. Your position as you describe
- it is definitely on the right track.

-
- Exactly so. The privacy gained by denying Postmasters the resources to provide
- such assistance is more marginal than most people think.
