That is a major issue here for some organizations in Qatar..I don't recall that there is such a way to make sure your applications are safe..I would recommend that you contact this company/organization by phone and be sure of the availability and verification of that e-mail address. I would try to send a copy or something by fax..If you cant get in touch with them either way. Look for a trustworthy third party or somebody you know who is already here..send him your information and applications so he can go to them personally..

Best of luck!
