I'm not quite that extreme. First, it's really only important for
automatic mails triggered as result of another mail (that's where the loop
comes in), and second, <> is only one of the options. Another is using an
address that won't trigger mails, which incidentally is the way good
mailing lists handle this problem. It all depends on what you're trying
too do.

It's somewhat silly for most "vacation" type usages, yes. Consider, OTOH,
a message telling the sender of an address change.
