To send a mail to all the users

[DarkBen]

I want to send a mail to all the users on my ISPConfig server. How could i do that ?
In fact i want to send à mail to all the users in the /etc/postfix/virtusertable file.

thanks for your help :)

If you use /etc/postfix/virtusertable as source for the mailing, many users might get more then one copy of the mail due to aliases and co-domains.

I think te easiest way might be to write a PHP script that reads the email accounts in the isp_isp_user table and sends an email with the php mail function to them. Maybe someone likes to write an extension / tool for ISPConfig?
