81272 Simple Newsletter script

Just need a simple newsletter script in PHP (preferred) and with flat text to hold the email addresses and basic functionality: - easy for users to subscribe/unsubscribe (just an input field and a button) - a place to show the admin the html code he has to place on his website to subscribe/unsubscribe - possibility for admin to add/delete/ban users - possibility to archive the sent newsletters to a webpage (preferrably static, no "?" in URL) - possibility to install the script in any directory - the admin part must be in a directory called /mailadmin/ - send a mail to admin when mailing starts and finishes - ability to set the from name, from email, priority and subject - ability to set welcome and unsubscribe message - ability to subscribe or unsubscribe users with or without the welcome or unsubscribe message - most important: not to leave a browser window open when the mailing is being sent. When a large list is sent (1000 email addresses) by using the mail() command the browser may get a timeout and the mailing will stop. Similar to the attached Mail Machine would be nice! Thanks and best regards, Reginald PS: To be added later, please do NOT include this in your price: - automatically send html OR plain text mails depending on what the user can receive - ability for admin to add more newsletters - individual welcome and unsubscribe messages per newsletter - connect to an existing database easily Please DO NOT quote for the items to be added later, just keep it in mind when you write the script.
