Eliot,

# Would ZMailer reconstruct the To: line by placing some bogus address?

No, the replacement address is exactly the corresponding envelope address
in all its gloryness.  If that too is bad, an earlier stage of processing
has already detected and rejected the message or compensated for the bogosity,
depending on the situation.

# <> can be replaced with an alias to an address linked to /dev/null, ...

Yes, however that means the code *requires* cooperation from the mail
administrator (to, say, put an appropriate nobody alias in place).  This
is not something I'd do without very very good reasons, since the required
cooperation is guaranteed to cause confusion and problems.  I think it is
bad enough that the various error messages needed by the code are kept in
external files, though in that case cleanliness won out.  As usual
it comes down to (personal) priorities and philosophy.

Karl,

Reminds me of my reaction when someone in passing told me "Oh, Henry got
his Sun", and the image that came and stuck to my mind was a little baby
with a Deep Authoritative Voice.  Sigh.

You can't know what it is like to be surrounded by anti-matter... there
is a vocal minimalist contingent at UofT, notably Geoff, Henry, Mark Bartelt,
and occasionally Norman Wilson.  You know the old story about never discussing
politics or religion with friends?  Well, header hacking comes in heavy in
those categories...  I think we all think it is a vile (tm Collyer) thing
but they seem to feel it is very rarely necessary whereas my experience
convinces me it is a necessary evil.

Then there was the time when I had made some changes to rmail... I
introduced a bug which caused messages longer than the stdio buffer
size to lose their second stdio buffer block.  I didn't realize there
really was a bug until I got a message IN SCREAMING UPPERCASE, from Henry,
complaining about his mail getting mangled.  It turns out that of all
the UUCP mail coming through the new rmail, mail from utzoo!henry was
the only stuff running into a problem.  You see, Henry's messages are
usually > BUFSIZ long.  I don't think Henry is quite convinced yet that
I wasn't purposely and personally targeting him (I wasn't Henry, *honest*!).

Still makes me blush.

We've since thought of some interesting variations on this scheme:
Henry-filters in the news system.  We could give him a signature of *our*
choice for a change...

Spencerisms:

The first line always seems to make     | Henry Spencer @ U of Toronto Zoology
a funny combination when read aloud.    |  henry@zoo.toronto.edu  utzoo!henry

This has been a test message of the     | Henry Spencer @ U of Toronto Zoology
constant broadcast system.              |  henry@zoo.toronto.edu  utzoo!henry

Anyone for a Usenix contest about       | Henry Spencer @ U of Toronto Zoology
signature quotes?                       |  henry@zoo.toronto.edu  utzoo!henry

This could go on forever, but a certain | Henry Spencer @ U of Toronto Zoology
daemon is going to get very grouchy.    |  henry@zoo.toronto.edu  utzoo!henry

;-))
