Notes/Troubleshooting

  • ldapbasedn is the base search, and it searches everything below it. Added OUs must be under this basedn in order for mail authentication to work.
  • to modify the tcp file, edit /var/qmail/control/qmail-smtp(auth).rules, then issue a make command from the /var/qmail/control directory
  • only users added to the listarchive group in AD will be able to access https://listarchive.computerisms.com
  • t64all is a command from your bashrc that is useful for watching interaction between samba and qmail-ldap. set -d3 or higher in samba's run script
  • wget http://qmail.jms1.net/scripts/qfixpermissions <= run this if you are having permissions issues
  • The LearnAsSpam folder should be disabled for users who can/do not understand the difference between usolicited mail and mail they don't want anymore.
  • the samba4 patch basically allows qmail to know if the account is active. All other values, such as must change password at next logon, return as inactive.
