I think that somethings goes wrong with IP detection and HOSTNAME.
After the operation i receive every time an email with those infos inside,
maybe during the parsing of those vars i get the die.

Already DONE, the headers are exactly the same, if I remove a mandatory
field i will get an error from the website asking me to complete all the
data in the form.

When there are all data inserted I get white page.
There is something after that block the operation.
