Thank you, that's good news (and I guess the temporary failure for local
delivery that Eric Wassenaar warns about should be fairly unlikely).
Some experimentation with SunOS's sendmail (a typical "stupid" one:-)
reveals that with the particular form above, 'user' is silently
*ignored* - however

user, |"/usr/ucb/vacation user"

works fine, and I believe that's the common organization anyway (don't
know where I picked up the one-address-per-line style).

Of course, this requires that the users disobey both aliases(5) and
vacation(1) (but they never read such things anyway, right?:-), and I
would still be interested in a more "general" solution.

It occurs to me that (at least in our case) it would be sufficient to be
able to detect that the address is quoted (where the definition of
'quoted' could be just "begins with backslash or is enclosed in double
quotes"), and if so send it to the local mailer regardless of what is
"inside the quotes" - but I don't suppose that would be possible...?
