Postini - howto
These days it is very easy to get your emails blocked and very difficult to reach anyone for an explanation, however after searching for ideas I found some things for Postini (email spam filtering company bought by google). Now it seems they are impossible to contact but they do have a tool too analyze Postini email headers, I am not yet sure how helpful it is.
From a false positive (my personal account to my work account (Postini scanned)):
X-pstn-neptune: 0/0/0.00/0
X-pstn-levels: (S: 0.14818/99.45382 CV:99.9000 FC:95.5390 LC:95.5390 R:95.9108
P:95.9108 M:97.0282 C:98.6951 )
X-pstn-settings: 2 (0.5000:0.5000) s cv fc lc gt3 gt2 gt1 ft lt r p m
X-pstn-addresses: from <mymail@manurevah.com> [db-null]
X-pstn-disposition: quarantine
Postini has a page with some long and boring concise and exciting explanations which in this case did not seem to fit the scenario. From what I understand the line X-pstn-settings shows a bunch of letter codes which correspond to tests, the ones that cause flagging should be capitalised. In this case none are, but still I'm spam.
After playing with my Postini user settings (and un-quarantining my mail) I sent another mail to my Postini filtered account:
X-pstn-neptune: 0/0/0.00/0
X-pstn-levels: (S:0.30681/99.70926 CV:99.9000 FC:95.5390 LC:95.5390 R:95.9108
P:95.9108 M:97.0282 C:98.6951 )
X-pstn-settings: 2 (0.5000:0.5000) s cv fc lc gt3 gt2 gt1 ft lt r p m
X-pstn-addresses: from <mymail@manurevah.com> forward (user good) [18/1]
The only differences are the "S" score in X-pstn-levels and of course the X-pstn-addresses. The S being the Spam score, and all the other points being the same, I am having a hard time guessing what has changed. The one thing that I see in the first header is [db-null] next to my (fake) email, which means I was not in the postini user's allowed recipients, now I am.
It's a complicated situation these days, you can't just write an email to someone saying your father has left you money that you cannot move out of the country and easily recruit people you have personally chosen to setup a Western Union money wormhole for you. You must be approved by your interlocutor in order to send them an email.
