Hi

Forgive me for posting with Outlook Express, but my work obligates me to use

much more.

Secure Hashing Algorithm 1
This is the revision of SHA [also called SHA0] which is an alogrithm to
produce a message hash [or digest] of a given file. Hashes are used to
ensure that a file is not tampered with since changing even one charachter
of a file will produce a different hash. Hashes are smaller than the
message, so they provide a means to check that a file was not changed.

So shouldn't the hash be at the end of the body, like PGP signatures?

It is, but there is a header `Hash: SHA1' near the beginning of the
body to indicate the kind of hash used.

By the way, hash function in elisp is available from

        ftp://ftp.jpl.org/pub/elisp/sha1.el.gz

First thing I do when plugged is log in to the corporate server, which
is also my pop guy, with a command like ssh -L1110:pop.work.com:110
work.com, type in my passphrase, and then have gnus slurp my mail from
localhost:1110. Works like a dream. Two-steps tho. I don't do
:prescript, and am not sure how the passphrase piece would work.

Following up to my own posts, I have narrowed it down to two bugs in
mail-source.

The first one is easy to fix.  In mail-source.el, there are a couple of
(partial) forms that look like this:

        (if (fboundp prescript)
            (funcall prescript)
and
        (if (fboundp postscript)
            (funcall postscript)

They need to be quoted:

        (if (fboundp 'prescript)
and
        (if (fboundp 'postscript)

otherwise the interpreter tests the fboundness of the string instead of the 
variable.

The second is a bit tougher for me to track down.  Colons in the program
string are converted to spaces.  That is, "1110:peorth.gweep.net:110"
becomes "1110 peorth.gweep.net 110".  Escaping with backslashes does not
appear to fix the problem (sigh).

Possibly more bugs to be found as I experiment.

Hmmm... turns out this is not a bug, but an artifact of what ps(1) reports.
So progress is being made... it'll be nice to be able to use my own code
again :).

No -- what we want to check is whether the contents of the variable is 
a function or not.  But we should first check whether it's a symbol,
since fboundp is kinda fragile.
