I think the problem is that SEARCH command returns to the main loop
while it waits for the indexing to finish. The main loop then notices
that the client has already disconnected.

So that kind of piping of commands isn't very reliable. This probably
works:

(printf "1 select \"INBOX\"\n2 search body quack\n3 logout\n"; read) | /opt/local/libexec/dovecot/imap
