Does the file you're trying to attach "pdf-curriculum" actually exist? My guess is it doesn't, because the filename doesn't even have an extension (.pdf for example)

Hello, the file exist and the name is [pdf-curriculum] => TET1-PDF.pdf
Extension are available.

    [email4] =>
 Array        (            
[recipients] => Array                (
                    [0] => curriculum@aaa.com
                    [1] => gestioneweb@bbb.com
                )            [subject] => .....
            [body] => ...
        [files] => Array(
                   [0] => pdf-curriculum)

TET1-PDF.pdf might exist but that's not what you've told your email to attach.

Hello, thank you.
i don't received email instead the problem it's not only attach...

So you've fixed up the file attachment? Because it won't send with an incorrect file name.
