That's a good clue.  `lmtp' appends `@unspecified-domain' to
unqualified e-mail addresses.  If your MTA strips the domain portion
from the envelope recipient, as sendmail does, the sieve vacation
handler will never generate vacation responses, because the envelope
recipient will never match the header recipient.  To make it work
here, I've modified imap/lmtpengine.c so that it appends the server
name parameter from /etc/imapd.conf, which is also the domain that
sendmail uses for masquerading.  This could be made more general by
using a separate configuration parameter.
