Hmm? This is not clear. Why smtps? It sounds like you should be implementing submission with TLS. Smtps is only needed to support inadequate, older Microsoft MUAs. Better clients and more recent Microsoft ones support STARTTLS. Beginners are usually better served by system users. The setup is much simpler, which is why you won't find many HOWTOs which cover setting it up. Whatever advantage you think you get from virtual users v. system users is probably imagined. On the Postfix side, start at: http://www.postfix.org/BASIC_CONFIGURATION_README.html For Dovecot version 2.x look around at: http://wiki2.dovecot.org/ and you can usually get by just reading through the files in /etc/dovecot/conf.d/ . > I recall reading in postfix docs that postfix cannot yet > authenticate for smtp against dovecot in this situation. I'm not sure what you read, but perhaps you confused client and server AUTH. Client AUTH means your server has to authenticate at another SMTP server, e.g., a relayhost. Dovecot SASL is only for server AUTH, which means clients (MUAs like Thunderbird) can authenticate at your server, and thus be allowed to relay mail. If you do need client AUTH, you also need to elaborate on what you are trying to do and why. Perhaps you are better off just using your current solution, not running a mail server at all. (See also http://www.postfix.org/SOHO_README.html for suggestions, if this is the case.) > Do I just need to set up a separate store of accounts (e.g. > sasldb) with the same account credentials?

The common thing I'm seeing is a poor description of the problem and goal. :) Try to clarify, in non-technical terms, what you want. -- http://rob0.nodns4.us/ -- system administration and consulting Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:
