Open Source Ticket System: Sending an advice at due dates?

... and accepting tickets from both logged in and anonymous visitors?

[Rosamunda]

Hi there!
Iīm looking for an Open Source ticket system that do these things:

= Accepts both logged in clients to post questions, and anonymous visitors.
= Send an advice to those customers who their payments are due date and they didnīt pay.

This stuff Iīve never saw it in any CRM before: The ability to work with tickets submitted via a form inside the webpage AND receive free emails sended by customers directely from their own personal email accounts.

Does this dream-system exists? :-)

Thanks in advance guys!

Seems excellent indeed!
The only prob is thatīs not Open source... ;-)

Iīve been thinking in SugarCRM or maybe Vtiger... as this last one is just a fork of the first, There are not much choices out there...
