Postini Email Security Trial

« Reply #1264 on 26/03/2008, 22:50 »
Postini/neptune would have caught it and dumped it in quarantine because of its sending behaviour. But AFAIK Plusnet are not using the neptune headers to tag these as spam.

We were incrementing the spam score where the X-pstn-neptune: qtine header was present as per the details here.
This would seem to have been replaced by X-pstn-neptune-cave-rslt: qtine. It's a 5 minute job to update the config but we need to be sure both headers serve the same purpose.
I don't think this is doing what's needed, Bob. Postini will send to quarantine any email that gets this result from neptune, however non-spammy it looks to the bulk filter. I think the neptune header(s) and the S: score are given for completely different reasons and shouldn't be mixed up in deciding whether an email is spam.

btw -- I've seen the old X-pstn-neptune-rslt: qtine header since we started getting the new X-pstn-neptune-cave-rslt: qtine headers -- but I can't find any documentation about the latter either....

I have been getting some SPAM through where In the header I have got the subject line in twice but slightly different, with the message SPAM marked, see below:- (These have apparently come from myself to myself but my address has been spoofed).

That is odd, is anybody else seeing this?
Yes, I've seen one or two of these. Unfortunately, I deleted them, but the style was like this:
Code:
Subject:    [-SPAM-]Some obnoxious medical piffle
Subject:S [-SPAM-]ome obnoxious medical piffle

Supporting Chris's comment why are emails marked with a blatant "x-pstn-xfilter:   y" spam rating by Postini not being marked as Spam 1 (thus being detained in my online IMAP spam folder and not deposited in my Thunderbird Inbox) by Plusnet?

I have a theory about this and it may explain some of the disparity between headers as reported by mikeb. Bear in mind this is a theory, so it will be interesting to see how things pan out. Whilst investigating this problem we discovered that an error had led to a number of domains being present without many of the mail filtering options enabled. This seems to have been accounts added *since*1st February. It could be that these accounts did not have BSB switched on. I'm wondering whether or not some of the unusual headers people have been seeing are those that are present in mail that's normally blocked as Blatant Spam.
I wonder if you're right, Bob, about headers that include X-pstn-status: off and have other headers very abbreviated? BUT I don't think your theory holds up with the perfectly well-documented X-pstn-xfilter:   y header! Postini say these are in breach of what they call a Global Rule, but I can't remember why they get past the BSB....

I've been on the Postini Trial since before Christmas, and I'm getting some of these.

Hasn't it been established that the duffed subject was something to do with a blank line in the middle of the headers?

I think that was a different problem. The blank line was causing the subject line to appear in the body of the email, and so it wasn't being tagged as [-SPAM-] when it should have been.  Here the emails *are* being tagged (twice!). As far as I can remember, the one I had on Tuesday didn't have anything else wrong with it and was handled correctly (which is why I didn't mention it at the time).

Hi, is there anyway I can tell if Postini is bouncing legitamite mail and if it is who they are from?

There are two things to consider. Postini will refuse what it thinks is blatant spam, with a bounce message to the sender. As far as I know, there is no way to find out about this without the sender making contact.

Presumably you know how your spam-handling is set up with Plusnet? You will need to have spam kept in a webmail folder, or delivered to your inbox, if you want to check for legitimate emails wrongly tagged as spam....

Hi, thanks, yes I get loads of legitimate mail marked as spam in my outlook folders. Lets hope that the legimate mail sender that may/may not, be bounced by postini, has the forsight to contact me by phone, otherwise I might be out of pocket. It seems strange that we need to use a system where we have little control over..

@cuke2u,

The level of control you have is soon to be greatly increased. Watch this space for an imminent blog post!

You will be able to choose to rely on Postini's quarantining as opposed to our filters if you prefer once the new Manage My Mail tools are available. This will be down to user preference.

That's useful to know.

OK, thanks for the clarificaiton.

If you come across any more examples with the double subject line then give me a shout and i'll get a problem raised to investigate why it's happening.

I tend to get several dozen messages a week containing the neptune header(s).  For instance, in the last week of Jan or thereabouts, I received 67 messages with the OLD flavour of neptune header.  Since then, I have received a not dissimilar quantity of messages with the neptune header each and every week but they have ALL been the NEW flavour neptune header. For instance, in the last 3 weeks, I have received 26, 31 and 33 messages with the NEW flavour neptune header.

YMMV and all that but show me a message with a recent date that contains the OLD style neptune header and I'll go and make some custard to pour over an appropriately sized slice of humble pie before consumption of same Tongue 

Mmmmmm, pie


What an absolute farce that we continue having to keep playing guessing games rather than being given clear and definitive information with all customers receiving a consistent and uniform service from what is supposed to be 2 professional companies providing a so-called state-of-the-art and reputable/reliable service. I take it there are still no definite answers from postini regarding the various undocumented features and apparent changes various then ?

I can't be bothered to google for "YMMV"  Cheesy but I'm going to be doubly sure to check for neptune headers in my mail in the hope of serving some custard  Cheesy
