PHP Helpdesk recommendation? (OSS or commercial/hosted)

[triffik]

Hi all,

I've tried a few PHP helpdesk systems, but none match quite my needs.
Can anyone make a recommendation?

Features essential:

• ability for members of the public to email a helpdesk email, which
  automatically logs a support query
• must not require (or even ask) members of the public to create and
  account on the system. We want to refer to the subjects purely by
  their own email address - not name, account, or anything else.
• ability to refer ticket to other helpdesk administrators

Features desired:

• ability for tickets to be created from a web page, without the
  user creating a support account
• ability to take notes on a query that aren't visible to the member
  of the public

Anyone know anything suitable?

Many thanks!

Joe

I too am in search of a web-based php/mysql based help desk system where the customer does NOT have to create an account to get service. The system should be able to accept Email requests as well.
