I' started receiving mails (both in MS Outlook and Outlook Express) in the following form:
-------------------------------------------------------

Does anybody know something?

Please, note that I checked the fact that one of the senders actually did send me the message. This makes me believe that we don't deal with viruses or spam.

Thanks!
