Well, using a simple mailbox_transport like shown in 2) is the easiest configuration. Of course you can have very complex postfix configs for example with complicated transport maps but you don't have to make it complex if your environment doesn't enforce it. > > 4) > And last but not least. How postfix authenticates in anyway so Cyrus ???? The question is how you want to communicate. In my case I was using a local trusted network between postfix and cyrus server so I did the easiest thing which is running lmtpd without authentication and configure TCP wrapper to accept only connections from the postfix host. Like so: In /etc/cyrus.conf I had lmtpd listening preauthenticated: lmtp cmd="lmtpd -a" listen="lmtp" prefork=1 In /etc/hosts.deny on the cyrus host I had: # Allow only specific hosts to send mail via LMTP lmtp: ALL EXCEPT mailhub.domain.tld Regards, Simon ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
