HQ only can store a 75 character string (maybe 100, my memory is failing me on that detail), so this will restrict you from doing it via the normal way in HQ.
Couple alternatives: 1. Create a control action script that goes and grabs the file and sends a secondary email with the whole script. You can connect this to the alert as an automated response if you have Enterprise.
2. Modify the email template to include a link that initiates the running of the same script. This is good for open source, but probably bad for running from a blackberry/web phone.
Both by the way, sound like great ideas that our community might like to see as a contribution. 🙂
