Most of my email is routed directly through Gmail as Tom's, but I still
get a few uncaught SPAM messages. Before my email goes to my Google
account, the BLU server applies its SPAM and SPF filters. I think I
received about 10 SPAM messages this morning. When I see some with
similar patterns, I go to gmail and report them as SPAM.
