[RndTbl] Gmail spam filtering super-aggressive lately

[Alberto Abrao]

Maybe if I try to type some more?

The headers now match the ones Trevor use.

Funny thing... I sent a brief message to my Gmail account and it went 
straight to spam.

Second one (not a reply, brand new) I decided to type some more, not as 
brief as the first one. Inbox.

So I wonder what will happen with THIS one?
