Security Error when Submitting a Form via Email

Acrobat monitors the type and number of attempts to access external resources by a PDF. This includes any media as well as actual web sites. With your form it's the email submit that's putting Acrobat over the edge so there must be something the form is doing before that point that makes Acrobat think another external recource is being accessed. Unfortunately Acrobat is not very picky about what gets it's hackles up. Several people have found things that don't make much sense.

This started to be a problem in Acrobat 8 because Adobe bumped up the security. So in Acrobat 9 they added a couple of mechanisms to help deal with the issues. One of these is the "Enhanced" Security preferences, which you'll find in the Acrobat preferences dialog. This isn't a lot of help on the form. Another mechanism is Cross Domain Files, which were originally developed for Flash. Here's an article:

However, if this form will be used by people with versions of Acrobat/Reader other than the one your are testing it on then it's best to try and avoid the problem all together, rather than trying to use some fancy security mechanism that may cause problems in future (or past) versions of Acrobat. Try to identfy what it is on the form that is causing Acrobat to think the form is accessing an external resource.

Thank you I will try this. This form doesnt access any external websites or resources..its a simple data entry and submit(via email) form. I hope the enhanced security function works.
