Sophos has an article about donation scams regarding the recent earthquake in Haiti.

The first example shows a long message which is supposedly from UK Red Cross. It wants the reader to send money via Western Union. SavioL, the author of the article, notes that the “From” email address does not say Red Cross. Also, the “Reply-to” adress is a webmail account which is typical of other scams such as the Nigerian/410 scams.

The second example also wants the reader to send money using Western Union.
