Which method of cyrus & sendmail integration do you use in sendmail.cf?

Standard implementation of LUSER_RELAY in sendmail.cf has been designed
for "OS accounts based local mailer" - achieving similar functionality
for "OS account less" mailbox system requires some "tweaking".

You can easily modify RTCyrus available at
http://open-sendmail.sourceforge.net/ to get
LUSER_RELAY functionality - in FEATURE(`anfi/vcyrus') replace error
mailer for "user unknown" with selecting specific cyrus mailbox.
