To handle a temporary situation in a few weeks where some local users will be undeliverable, I want to queue up mail for those users for a few hours, and then release it when it will work again. Quarantine looked like a nice solution but it's not working for recipient addresses.

When I put this in access file... From:x...@columbia.edu QUARANTINE ...it quarantines mail from that address as expected.

But I need to do it by recipient like this... To:y...@columbia.edu QUARANTINE ...and this is ignored. It should work with a To: address, shouldn't it?

Do you have
FEATURE(blacklist_recipients)
in your mc file?

Try your config in -bt mode:
http://www.sendmail.org/~ca/email/chk-dbg.html

Problem solved! Thanks again, Claus.

For anyone else who reads this... FEATURE(blacklist_recipients) is needed in order to quarantine by recipient. Then it's all good, done as follows.

access file:
To:sp...@columbia.edu QUARANTINE:foobar

makemap hash access < access, then check with -bt:

# /usr/sbin/sendmail -bt
ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
Enter <ruleset> <address>
> /map access To:sp...@columbia.edu
map_lookup: access (To:sp...@columbia.edu) returns QUARANTINE:foobar (0)
> Rcpt_ok sp...@columbia.edu
Rcpt_ok input: spam @ columbia . edu
ParseRecipient input: spam @ columbia . edu
CanonAddr input: spam @ columbia . edu
canonify input: spam @ columbia . edu
Canonify2 input: spam < @ columbia . edu >
Canonify2 returns: spam < @ columbia . edu . >
canonify returns: spam < @ columbia . edu . >
Parse0 input: spam < @ columbia . edu . >
Parse0 returns: spam < @ columbia . edu . >
CanonAddr returns: spam < @ columbia . edu . >
ParseRecipient returns: spam < @ columbia . edu >
SearchList input: < + To > $| < F : spam @ columbia . edu > < U : spam @ > < D : columbia . edu > < >
F input: < spam @ columbia . edu > < ? > < + To > < >
F returns: < QUARANTINE : foobar > < >
SearchList returns: < QUARANTINE : foobar >
Rcpt_ok returns: $# error $@ quarantine $: foobar

At port 25 all looks normal (done from another host):
rcpt to:<sp...@columbia.edu>
250 2.1.5 <sp...@columbia.edu>... Recipient ok

And here it is, quarantined:
# ls /var/spool/mqueue/
dft4QE86m2032233 hft4QE86m2032233
