How to hand over mails from postfix to cyrus

[Pascal Gienger]

Like I already told you in the postfix-users-list, the best way to do local 
mailbox delivery with postfix and cyrus is using lmtp over a local socket 
(if both services are on the same machine).

Cyrus lmtpd expects a valid user/mailbox name as local part. So create 
valid address to sasl usernames using a postfix virtual table. I described 
it for you on the postfix-users list because this is not a cyrus imap 
problem. ;-)
