This might be a PEBKAC on my end, but in our old server, "vacation"
responses would only be sent back to an origin address once per day
because we had ":days 1" in the rule.
On the new server, even though we have ":days 1", pigeonhole is sending
responses to every message, resulting in multiple vacation responses
each day back to each origin address.
The following was generated by Roundcube's web interface, it looks to be
correct.
-----------------------
require ["vacation"];
# rule:[vacation-reply]
if allof (not header :contains "Subject" "[spam]", not exists
"List-Unsubscribe")
{
vacation :days 1 :addresses
["ema...@example.com","ema...@example.com"] :subject "Out of office
reply" text:
I am currently out of the office July 11th and 12th, returning on July 15th.
During this time I will have no access to email.
Thank you.

Interestingly, if I look at .dovecot.sieve.log, I see error messages
like (except that the vacation responses are, in reality, being sent):
error: msgid=<20130711134816.35b9a40...@mail.example.com>: failed to
send vacation response to <originem...@example.com> (refer to server log
for more information).
And in the maillog:
Jul 11 09:48:17 servername sendmail[28244]: r6BDmHem028244:
SYSERR(UID1132): Who are you?
Jul 11 09:48:17 servername sendmail[28244]: r6BDmHem028244:
Authentication-Warning: servername .example.com: Unknown UID 1132 set
sender to <> using -f
Jul 11 09:48:17 servername sendmail[28244]: r6BDmHem028244: from=<>,
size=725, class=-60, nrcpts=1,
msgid=<dovecot-sieve-1373550497-20224...@servername.example.com>,
relay=Unknown UID 1132@localhost
My guess at this point is that I've failed to configure pigeonhole
and/or postfix's copy of the sendmail command properly so that it can
create the "who I have send mail to recently" file.
