You are right about the pre-authentication on a unix Socket. It is always turned on. Postfix has no lmtp-Server, so he does not need to disable something. The Unix Socket in Postfix which is named lmtp is the Socket from the Postfix Internal Side to it's lmtp-Client. I don't think this is a problem with/without pre-authentification. The lmtp-Server in Cyrus-IMAP uses the given proxy_authname/*_password, regardless of the credentials used in the connection to the lmtp-Server. > Maybe other folks know of a cleaner way to do this, or have other > suggestions. -- Andreas ---- 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
