Have you sent yourself test emails? (I've sent some through from Google to check the headers in the last half hour and they arrived in seconds)
Have you sighned up for the Postini trial?

The changes were completed in the early hours of this morning.
We'll need to wait for DNS changes to propogate, but then you should see the changes.

Quote from: Bob It will take up to 48 hours for DNS to fully propagate but once it has your MX records will look a little like this: ;; ANSWER SECTION:
username.plus.com. 86400 IN MX 10 mx-postini.core.plus.net.
username.plus.com. 86400 IN MX 20 mx-postini.last.plus.net.
My username.plus.com records look like that, but what should the MX records for our hosted domains look like? Mine are absolutely nothing like that.

Bob might be able to check further, but we said it would take 48 hours for all the changes to take place, and I think until that time has expired you need to exercise a little patience (please!).

(I assume you were doing the sensible thing and checking on the authoritative servers for the domains (ns1 & ns2.force9.net and not some caching server)

I usually get a steady stream throughout the day - the only spam I've received since 9am didn't go through Postini (i.e. using the old DNS entries). That is most unusual.
The (very) early signs look highly promising.

Eager to see how this pans out for those who get lots of spam to their accounts. Even with the Webmail Incident there's only about 12 a day delivered to my PlusNet account so I've not been able to see it first hand (apart from on the internal mail platform which is a slightly different beast).
Just a reminder that at this stage it will only affect volumes reaching your mailbox and not the amount of messages that are tagged/not tagged.
I'll need to check this but I don't think we've blocked the email yet that will be getting sent by spammers directly to the mx.last and mx.core virtual hosts either. This means that some stuff has the potential to bypass Postini. On the internal mail platform we block anything that doesn't come via Postini and this is ultimately what we'll do for customers once we've allowed time for the changes to bed in.
At the moment you may get email that's taken any of the following routes -
- Sender > Postini > Critical Path > mx.cores > You
- Sender > mx.last > You
- Sender > Critical Path > mx.cores > You
- Sender > Postini > mx.last > You * not very likely this one

I don't usually get a lot - but enough to notice the difference (around 10 an hour) - they have stopped totally. But I haven't received anything tagged via Postini (by Postini in the headers or by DSPAM) - but then most of what I was receiving was such obvious junk I have no qualms about Postini totally binning it.

Quote from: jelv Would errors I've suddenly started getting on a Perl sendmail based script on ccgi be anything to do with these changes?
If the from address is your domain then I guess this is possible. I'd need to chase it up.
Quote As there are no references to mx.core and mx.last in the new DNS entries isn't the only way we could get email direct to those is if they are using cached old DNS entries? If that is the case surely after a few days those should virtually disappear so I'm puzzled as to why they may need to be blocked.
You'd be surprised jelv, trust me. I have a domain that hasn't used Plusnet's mail exchangers for well over half a year and spammers still send email destined for my domain to our mx.last and mx.core servers. This was certainly an eye opener for me when I realised it was happening as I originally thought along the same lines as you.
