Hey, Had some trouble initially with SASL when I upgraded Ubuntu. In /etc/postfix/sasl/smtpd.conf I had to change the following: Code: auxprop_plugin: mysql sql_select: select password from mail_user where login = '%u' to sql_select: select password from mail_user where login = '%u@%r' auxprop_plugin: sql Moderately annoying to figure out.
