Joaquim,
1) Have mail sent to help...@mydomain.com inserted as a ticket
into the system
You need to configure your email server in such a way that all emails sent
to helpdesk@ are saved in a specific folder. Then create an IMAP/POP3 email
account in Eventum, and setup a cron job to regularly download emails saved
in that folder.
2) Have the sending user receive an automated ticket response
The sending user can receive an automated response, but you will need to
create a ticket for the email in order for this to happen. See the
'Auto-Creation of Issues' link after you create your email account above.
3) Have this done so that the "filter" is invokved via the
.qmail-file (this
lessens the load on the system, instead of having to have cron
handle this).
If you want to have qmail process emails sent to a specific address, then
the email routing feature is exactly what you want. It will handle emails
sent to a specific address like issu...@support.example.com, but you need
to setup qmail to make this happen.
Have qmail run the /path-to-eventum/misc/route_emails.php script, passing
the associated email account as the first argument to that, and pass the
full email as standard input.
