I've taken a 3 day trial to Document Hawk to be able to open/view doc and pdf attachments on my BBerry. I've configured my BB exactly as Document Hawk instructs but every document that I submit to Document Hawk comes back to me as undeliverable. I'm decent technogically but not enough to understand the gibberish on the SpamCop site. I need this feature to continue my business while traveling. The message that I get is that my document submission to Document Hawk was undeliverable...that the reason for the problem: 5.10.......Unknown address error 554-'5.7.1 Rejected. DUH???? What can I do to rectify it and receive the docs back from Document Hawk for viewing. How can I unblock my email address???
