Request: Allow support addresses to create a ticket via email.

To start with the use case:  it's not uncommon that we need to initiate an email to one of our customers (e.g. "Let us know when you have logged off the virtual machine so that we can expand the memory").  We want to send that from our primary support email (support@mydomain.org) so that any replies will be delivered to Zendesk.  But we'd also like to copy zendesk with a CC copy of that original email so that we have a ticket in Zendesk to track the communication, particularly so that we can follow up if we get no response).

Unfortunately, at the moment, because that initial email has a reply address of the primary support address, the ticket is suspended.  This means that today we simply do not include support@mydomain.com as a cc address; if the user replies, we get a ticket, but we need to track this communication separately to cover the case that the user does NOT reply and needs followup.  And of course having separate systems to track follow-ups is less than ideal!

My proposal - if the domain of the support address is included on the white-list of allowed domains and addresses, this would override the suspension of messages from  the support address.  Or perhaps we could be a bit more specific, if the individual email for the support address is in the white-list, this bypasses the suspension.
Less desirable alternative: if there was some keyword that we could place into the message that would tell the code determining whether to suspend the ticket that this was intentional, then that could be the trigger for the override.  Something like "action:create_zendesk_ticket" would virtually never occur naturally in a message (avoiding false positives); if we embedded it by hand in our email signature, it wouldn't be too obtrusive to the recipient of the email.
