Use courier-imap to auth for postfix with encrypted passowords in mysql

Hi, I used your postfix howto but sasl sucks with encrypted passwords from mysql and postfix.admin. Based on information in the following pages: https://www.brandonchecketts.com/archives/configuring-postfix-sasl-to-authenticate-against-courier-authlib https://www.thelazysysadmin.net/2009/08/cannot-connect-to-courier-authdaemond-no-such-file-or-directory/ https://askubuntu.com/questions/303120/how-folders-created-in-var-run-on-each-reboot I used courier-imap to do the authentication, and it needs: a) as my postfix is chroot we should move the socket of the courier-authdaemon (courier should be shutdown): mkdir -p /var/spool/postfix/var/run/courier/authdaemon rm -rf /run/courier/authdaemon ln -s /var/spool/postfix/var/run/courier/authdaemon /run/courier/authdaemon b) use the following contents in smatpd.conf in /etc/postfix/sasl pwcheck_method: authdaemond mech_list: PLAIN LOGIN authdaemond_path: /var/run/courier/authdaemon/socket c) as /run is recreated in each reboot, we should ask the system to recreate the symlink by adding the following line in file eg courier-authdaemon.conf in /etc/tmpfiles.d/: L+ /run/courier/authdaemon - - - - /var/spool/postfix/var/run/courier/authdaemon

Postfix now can use courier-IMAP for authentication the smtp clients

Interesting. I will have to take a look at that.
