I understand you want to use Dovecot as SASL provider. In this case the configuration (see below) you are currently trying to use is leading you completely the wrong way.
Take a look at the section "Configuring Dovecot SASL" in the SASL_README (/usr/share/doc/postfix/SASL_README.gz> that is shipped with Postfix. Here's what you basically need to do: 1. Configure Dovecot to provide an authentication socket for Postfix 2. Configure Postfix to use that socket. Step 2 might be a little extra complicated if you run your Postfix server chrooted, which is the default on Debian/Ubuntu machines. p...@rick __________________________________________________________________________ Ok I have done all that was aked by the documentation but... I noticed that I have another line for passdb pam { mine appears to be linked to mysql passdb sql { args = /etc/dovecot/dovecot-crammd5.conf my mechanisms = plain login also had " crammd5" at the end of it. Would this make a difference or do I now need to try to do this through mysql. I started to read up but stopped as I thought I would be ok this way. Thanks.
