Why does the preflight report have a problem with the From section?
Many templates, including those intended for distribution in the US, have a built-in Address section at the bottom to comply with anti-spam laws. If the profile being used in the From address does not have address details saved in it, your preflight report will display the following in the From section:
"Profile is missing some information. Address details are required."
To resolve the issue, you will need to edit the profile to include address details.
