SpamSieve classifies USPS as Spam

Why would SpamSieve treat a USPS email as Spam? It does have my email address in the “From” address - uspostalservice_at_usps.com_sequitor@duck.com is that the reason?

“You trained this message as Good from your mail client.
Prediction: SpamSieve had predicted this message to be Spam, and you corrected the mistake. SpamSieve’s Bayesian classifier predicted this message to be Spam based on a statistical analysis of its content.
Score: 73 (0 is least spammy; 100 is most spammy)”

Should I change my Score value?

Thanks

That’s a strange looking address, but it doesn’t seem to be the reason. What does the Words section of the log entry say?
