Hi all, I have set up postfix with a my sql database and every thing works well with the postfix lda. But when I switch to maildrop I get the following log message: Jul 24 11:47:40 alg-network postfix/cleanup: 0FD6614A1A8:message-id=<[email protected]> Jul 24 11:47:40 alg-network postfix/qmgr: 0FD6614A1A8: from=<>, size=286,nrcpt=1 (queue active) Jul 24 11:47:40 alg-network postfix/pipe: 0FD6614A1A8: to=<[email protected]>, relay=maildrop, delay=0, status=bounced (user unknown. Command output: Invalid user specified. ) Jul 24 11:47:40 alg-network postfix/qmgr: 0FD6614A1A8: removed every thing seems like maildrop is not looking to the database my /etc/courier/authdaemonrc authmodulelist="authmysql" authmodulelistorig="authmysql" daemons=5 version="" authdaemonvar=/var/run/courier/authdaemon my /etc/courier/authmysqlrc MYSQL_SERVER localhost MYSQL_SOCKET /var/run/mysqld/mysqld.sock MYSQL_USERNAME dbusername MYSQL_PASSWORD dbpass MYSQL_DATABASE mail MYSQL_USER_TABLE email MYSQL_LOGIN_FIELD username MYSQL_CLEAR_PWFIELD userpassword MYSQL_UID_FIELD uid MYSQL_GID_FIELD gid MYSQL_MAILDIR_FIELD virtual_mailbox I am suspecting that authmysqlrc is not parsed! I tried to introduce some errors to see if some thing is logged in the syslog file but nothing hapends! However authdeamon is effectively parsed in the /etc/courier folder I tryed to activate the maildrop log but I didn't findout how! one more information, here are the packages I installed: ii courier-authda 0.47-4sarge5 Courier Mail Server - Authentication daemon ii courier-authmy 0.47-4sarge5 Courier Mail Server - MySQL authentication ii courier-base 0.47-4sarge5 Courier Mail Server - Base system ii courier-maildr 0.47-4sarge5 Courier Mail Server - Mail delivery agent does any one know how to activate the maildrop log? does any one know where authmysqlrc is supposed to be? thanks for your help one more element, I tried with (authmodulelist="authuserdb") and it works! so it seems like it is directly related to the authdaemonrc! any idea? or maybe a link to a potential solution?
