First thing, don't go "on the net" for this. Start in the documentation. Read the sources to which it refers if you need general help. Also, wikipedia is pretty good on covering email basics. The BASIC_CONFIGURATION_README.html covers issues that need to be addressed on every Postfix install. Note the part where it talks about "relayhost" ... that is the ISP server. The ISP will run a MSA (mail submission agent) for their users. SASL AUTH is an essential element of this. See SASL_README.html for the details. That covers setting up the "home" instance to authenticate with the ISP, and covers setting up the ISP to handle that. For client AUTH, Cyrus SASL is the only supported option. For server AUTH (the ISP), you can choose Cyrus or Dovecot for SASL. IMO the latter is much easier and nicer to work with. STANDARD_CONFIGURATION_README.html does not specifically cover what you're talking about, but is worth a visit. All of the aforementioned HTML files can be found in your own $html_directory, as well as online at http://www.postfix.org/ . Be sure to browse the other titles in the $html_directory while you are there. I keep a link in my browser for ready reference. -- http://rob0.nodns4.us/ -- system administration and consulting Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:
