Post your cyrusv2d definition from sendmail.cf.
  echo '=M' | sendmail -bt | grep cyrusv2d

Does it contain F=u flag?

By default sendmail's mailers convert user part of recipient address to
lowercase. F=u flag stops it. 
*BUT* it would apply to "normal recipients" *too*.

Does smmap return "unknown user" *even for lowercase folders*?

It merely a matter of choosing a simple way you like anyway :-)

Why have not you tried RTCyrus3 recipe?
[ It would require small "patching" too to meet your requirements ]
