Andy, According to your suggestion, my IMAP login is working now. I can now connect imap clients through my frontend servers to access mail boxes in the backend node. However, I still _failed_ to deliver mail via Postfix LMTP through Cyrus LMTPProxy running on the frontends to my cyrus-imap backend server: [Log Message in my frontend Server (mail.sb.marshall.edu)] lmtp[22156]: couldn't authenticate to backend server: no mechanism available postfix/qmgr[12870]: 232871D0012: from=<nahant-list-bounces@xxxxxxxxxx>, size=3881, nrcpt=1 (queue active) postfix/lmtp[22309]: 1EB811D0013: to=<xxxx@xxxxxxxxxxxxxxx>, relay=/var/lib/imap/socket/lmtp[/var/lib/imap/socket/lmtp], delay=-940, status=deferred (host /var/lib/imap/socket/lmtp[/var/lib/imap/socket/lmtp] said: 451 4.4.3 Remote server unavailable (in reply to end of DATA command)) [Log Message in my backend Server] mailbox1 lmtp[31162]: accepted connection mailbox1 lmtp[31162]: connection from mail.sb.marshall.edu [10.101.4.251] preauth'd as postman I found there is NO such user named "postman" on my backend server. But Cyrus LMTPd authenticated the frontend LMTPProxyd as this user.
I ran into this problem too. In my standalone Cyrus config, I was using "lmtpd -a" (preauth). When I tried to setup Murder, I couldn't make preauth work with lmtpproxyd. I had to turn off preauth on the backend server and configure Postfix to use lmtp auth when it connected to the frontend server. I actually posted this to the list about a week ago, but here is what I did:
In postfix's main.cf: lmtp_sasl_auth_enable = yes lmtp_sasl_password_maps=hash:/etc/postfix/lmtp_passwd lmtp_sasl_security_options = noanonymous In /etc/postfix/lmtp_passwd: cyrus-fe1.onid.oregonstate.edu cyr_lmtp:password In imapd.conf on the frontend server: lmtp_admins: cyr_lmtp proxy_authname: cyr_proxy In imapd.conf on the backend server: lmtp_admins: cyr_proxy proxyservers: cyr_proxy Andy ---- Cyrus Home Page: http://asg.web.cmu.edu/cyrus Cyrus Wiki/FAQ: http://cyruswiki.andrew.cmu.edu List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
