I get this error when creating a new user USING POSTFIX ADMIN - ************************** DEBUG INFORMATION: Invalid query: Duplicate entry ‘postmaster@hiringexpress.com (61.9.18.12)’ for key 1 ************************** - but the user is created in the Mysql Database though the Mailbox Directory are not created. - when I edit the config.inc.php in line where it states postmaster@hiringexpress.com to another name, it creates the new user and Mailbox Directory with no errors, but if i create a new user again it shows the same error message, that’s why I have to keep changing the same line in config.inc.php to make it work. Are there other ways in fixing this problem? - I have already followed the Functions.inc.php EDITING from http://switch.richard5.net and all of the other websites suggestions.
