Yes, but only once I added the F=u flag to the m4 file
(MODIFY_MAILER_FLAGS(`cyrusv2d', `+u') in the sendmail.mc didn't work).

mailer 4 (cyrusv2d): P=[IPC] S=EnvFromSMTP/HdrFromL
R=EnvToSMTP/EnvToSMTP M=0 U=-1:-1 F=1DFMXlmnqsuz L=0 E=\r\n
T=DNS/RFC822/SMTP r=100 A=FILE /var/run/cyrus/socket/lmtp

Thanks !

That whas my understanding as well.
but it's ok, since lmtp_downcase_rcpt: yes takes care of the username part.

Nope, you're right. the real problem is on the mrs check, then. If I
create a lowerrcase folder along the mixed cased one, the mail is
received in the correct folder (that is, the mixed case).

Actually, I was adding a new backend in an existing murder environment,
migrating existing users and public folders from MS Exchange server.
Since rtcyrusv2 "just works" in the existing environment, I didn't even
check if there was an update. I saw about RTCyrus3 only when searching a
solution to my public folder problem.

if it can resolve the mrs_cyrus_mailertable problem, and if it's not too
difficult to upgrade rtcyrus2 with it, I'm willing to give it a try.
