If you have come here because you think you have received spam from the pennypacker.org domain please rest assured that this is not the case. Spammers routinely forge the "From" address in the spam they send out, and a spammer has apparently decided to use this domain for just such a purpose.
If you are an end-user and would like to fight back against these kinds of forged spams then please contact your e-mail administrator and encourage them to consider implementing SPF (Sender Policy Framework). This is a system designed to help prevent spam forgeries, and this domain is an active participant. In the month of July, 2006 SPF alone blocked over 500 spam e-mails to this domain.
If you are an e-mail administrator then please implement SPF in your e-mail servers. It's easy to set up and will help you to identify and potentially block a significant amount of spam. Your end users will thank you!
