Attached without Attachment

Hi all, i made a code in PHP to save in a directory the XML attachments ! All goes well until it comes across an email that has attachment but can not save ! analyzing the source code of this email, i realized it has no line: Content-Disposition: attachment; filename="name of the file.xml" but only this line: Content-Type: application/octet-stream; name=name of file.xml Content-Transfer-Encoding: base64 I´m using IMAP and the account is from Google: $host = "{imap.gmail.com:993/imap/ssl}INBOX"; What happend ? Thanks any help Gustave
