Hi Andy,

I was so
surprised to actually find a domain that used -all that I immediately
put on my ``for science'' hat and proceeded to test.
twitter.com and amazon.com are two others with `-all' IIRC.
i'm surprised at the surprise. it's the only tool available to
reduce the impact of forged spam -- i.e., someone sends mail
pretending to be me, and then i inherit the bounce storm. i don't
know that -all is the sole reason, but i haven't had one of those
bounce storms in years. it could be inconvenient at times, i suppose,
but hasn't been for me. i run my own primary smart host, but to
allow occasionally sending mail from gmail with From: set to my
home address my SPF includes the google SPF block:
$ dig foxharp.boston.ma.us txt
foxharp.boston.ma.us. 1799 IN TXT \
"v=spf1 mx ip4:173.48.171.74 include:_spf.google.com -all"
(the IP address is my home internet connection, which isn't an MX for
my domain.)
A larger space indicates to me a significant break, e.g. end of
sentence. Lack of hyphenation means many spaces are becoming two in
your formatting, creating ugly rivers of whitespace. These are a
problem in typesetting of proportional fonts fully justified;
fixed-width doesn't have a chance. Subjective, I agree.
It also breaks vim's formatting of the `> ' quotes lines above, i.e. it
preserves the multiple spaces thinking they're significant.
huh. finally something that vile unequivocally does better than vim. ;-)
