From: Jeff Lacki on 11 Feb 2010 18:13 Im trying to setup SASL+TLS+dovecot. Overall Ive gotten things somewhat working, but have a couple questions since Im new to this aspect of postfix. I get 'fatal: no SASL authentication mechanisms' in maillog I ran saslfinger and it showed no mechanisms, my /usr/lib/sasl2/smtpd.conf contains: pwcheck_method: saslauthd mech_list: plain login saslauthd is installed and running I dont think it matters, but I have what many others said they were missing: cyrus-sasl-plain installed. Am I supposed to add other 'mechanisms' and if so, how do I do so? Which packages do I add etc?

Not exactly, Ive been reading all kinds of docs and since Im new to some of it, Im a little confused between SASL and TLS. I've used postfix for a while but never dove into the encrypted aspects of things for security. Now Im trying to get secure. I was reading http://www.postfix.org/SASL_README.html to get SASL+TLS (hopefully) setup to allow specific users to relay through my server securely, but maybe Im completely going down the wrong path? I appreciate the help.

Instead of random websites, you may want to take a look at the much updated and expanded SASL_README file. http://www.postfix.org/SASL_README.html Wietse

The parameter, is documented at http://www.postfix.org/postconf.5.html#smtpd_tls_auth_only if you take a moment to reflect on the "yes" setting, you will understand why tools that probe the list of available SASL algorithms may find none. -- Viktor.
