# UNIX Hierarchy Convention
# Set to yes, and cyrus will accept dots in names, and use the forward
# slash "/" to delimit levels of the hierarchy. This is done by converting
# internally all dots to "^", and all "/" to dots. So the "rabbit.holes"
# mailbox of user "helmer.fudd" is stored in "user.elmer^fud.rabbit^holes"

# Rejecting illegal characters in headers

# Munging illegal characters in headers
# Headers of RFC2882 messages must not have characters with the 8th bit

# crappage untouched by disabling this (if you don't care that IMAP SEARCH

# Forcing recipient user to lowercase
# Cyrus IMAPD is case-sensitive.  If all your mail users are in lowercase, it is
# probably a very good idea to set lmtp_downcase_rcpt to true.  This is set by
