Due to the increasing amount of spam, we are using more aggressive spam filters. Your email may be filtered if you do not hear from me within a week.
Possible actions of filtered "spam" could be: send a bounce message, discard the email, forward to another email address or save the mail in a spam folder. Please try to send me a plain text email (not even in html) without any attachment.
Another option is try to send a message to a colleague of mine as everyone uses different spam filters.
