It's just a guess based on experience.  I answer the question, "Does
that look right?"  For "a!b@c", or "a!b!!!", etc. the answer is: "No."

Such a rewrite cannot improve the address, yet it can easily degrade
it, due to the Slings And Arrows Of Outrageous Header Munging
(SAAOOHM).  If that's not Evil and Rude, I don't know what is.

Well, of course translation is possible.  That doesn't mean, however,
that such a translation has no semantic meaning.

Sites that assume that "dom.ain!user" is equivalent to "user@dom.ain"
and therefore rewrite the latter into the former cause problems,
because that equivalence is not universal.  It is common, yes, but
not universal.

Granted, a site that fits all E-Mail into the Procrustean bed of
RFC822 may have to assume that "dom.ain!user" means "user@dom.ain" for
mail arriving via UUCP.  (For example, Ohio State does so.)  I have no
objection; handling a UUCP->Internet gateway is an exercise in making
best guesses, from all I have read.

But on the way out from the Internet onto UUCP, I see no excuse for
scrambling the syntax of header addresses into "dom.ain!user" on the
assumption that the reworked syntax will be "treated the same."  It
ain't necessarily so.
