Permissions on submitting .pdf forms by email

[Zoe Bourne]

Greetings all,
Firstly, a thanks to the developers of Scribus - I'm very new to this but it's been a good experience so far with excellent support from the wiki.  All power to you guys!
One little problem: I've created an interactive .pdf form and used mailto: as the Submit action (as per instructions in How to create an e-mail PDF survey) but when I tried submitting it, I got an message saying I did not have permission to access the server for mailto:the-address. Was this because I was testing on a localhost server or is there something else I don't understand?
Thanks in advance for your help.

can you please share the pdf? (or a simpler version of it)
it makes it easier to test what the issue is...
ciao
