I just tried this on my postfix/cyrus server using very similar revisions
of both, and appear to have exactly the same problem. The upside is, I
probably lose a lot of spam this way. I found the thread on
lmtp_downcase_rcpt, but noticed that my imapd.conf(5) page doesn't mention
it, so maybe it was introduced in a later version of Cyrus?
