For a few months i've happily been using the "Comments: Authenticated
sender is..." header to filter out spam. Till now it has worked great -- never
nailed a legitimate message. However, today it did return a false positive.
Below are the headers. Did i miss anything?

ESRI-L is a valid mailing list. Since there were no X-PMFLAGS, X-Mailer, or
Resent- headers, i'm not sure what else to look for.
Thanks in advance for any tips,
