I have tried twice before to set up SASL authentication for Postfix and failed to get it working both times. I am now trying a third time.
I have three remote mail servers to which I can send outgoing mail. I use Balsa as a mail client and, as a test, I set the value of the Remote Server, in the Balsa settings, to each of the three mail servers in turn together with the appropriate values for username and password. I sent an email using each setting and they all arrived. This shows that my username/password combinations are correct for each of the remote servers. I then created an /etc/postfix/sasl_passwd file and transferred the values for all three servers in the form: server.name username:password I then ran postmap hash:/etc/postfix/sasl_passwd. So far so good. Before I go any further I'd like to check the format of the sasl_passwd file. I have seen the form shown above on various howtos after searching on the Internet but I have also seen them where the server is encased in square brackets - [server.name]. Are those brackets required? Having got an answer to that question I'll carry on with the SASL setup and will probably be back with further questions. -- Barry Samuels http://www.beenthere-donethat.org.uk The Unofficial Guide to Great Britain
