Well, its rejecting the email based on the MAILFROM but you changed the MAILFROM to elbar2@testdomain.com (I'm assuming that you don't actually own testdomain.com) so there isn't much we can do about that issue until you provide legitimate details.

Most spam filters offer you the option of blocking by country (in the MAIL FROM)  Perhaps this is what's happening.

A few years ago, we were receiving a ton of spam email from Romania so we blocked everything with a .ro extension.

Note: I just realized the .es top level domain is Spain and not Estonia.  I doubt anyone would block all email coming from Spain though.  Your server ip isn't bloacklisted either: http://www.senderbase.org/senderbase_queries/detailip?search_string=217.160.6.244

Perhaps contact the server's admin? Or post the issue on MagicSpam's forum?  http://forums.wizard.ca/viewforum.php?f=4
