I have designed a form in Adobe LiveCycle Desgner some years ago. The users send a converted xml-file by e-mail (automatically via "send by e-mail-button") after haveing filled in the form. Recently a user updated to Windows 7 and windows mail (I think it is called windows mail, at least it is not Outlook), and from then he can not send any longer.
Why is this? Is it Windows 7 that is the problem or is it some configuration in the firewall/virus detection program?
