OK, I have recently decided to try out Google Postini.  For the most part, their part of the deal is working great.  But there's a problem - MOST of the messages are not going to Postini.   Here's what I've done so far.

By the way, I'm running a dedicated server.  I'm trying out one email address, and if I can get it working, I'll add many, many more.

So, the original MX record has been removed and replaced with the four MX records that Postini provides.  It's been four days, so propogation should be done.

So, I'd say that 80-90% of the spam I receive is still coming to my mailbox.  The Postini account is configured right, as far as I can tell, because it's snagging spam and sending me the daily updates.  The spams that are caught by Postini show their server info in the headers.  However, the much-larger quantity of messages received do not show any Postini info in the headers.  Tech support thinks that the spammers are using my account to send out the spam - but 80-90% of the messages?  I don't know, doesn't sound right.

We set up port 25 on the box to reject all requests except those from the Postini server IP addresses, but then all of my resold accounts suddenly couldn't send out email!  Postini hasn't offered up any smtp server settings, so I'm at a loss there.  Tech support said that they'd keep the port 25 block in, but they added my home DSL IP to the list of Postini IP's so I could email from home.  But then my resold accounts are all dead.

It's almost as if the MX record changes didn't take - but they did. 

Also, I've gotten conflicting information about whether the MX records should be listed as localdomains or remotedomains.  If I put the domain name in the remotedomains file and remove it from localdomains, then all of the mail seems to get processed by Postini, but when I try to email to the address in question, say, from Yahoo, I get a message saying that the message delivery failed because relaying isn't allowed.   If I put the domain in the localdomains and remove it from the remotedomains, the mail comes in but the spams are all there and Postini doesn't show up in the headers.   Arrrrrrrrrrrrrrgh.

So, great, I get 700 spams per day on this account, and Postini is only seeing about 30 of them per day.  BUMMER!!!!!!!!!!!

SpamAssasin was grabbing most of them when I was using it, but you don't get the option of seeing (daily) what it grabbed and offered to recover the messages held.

There has to be an answer!  Has anybody properly configured this on their dedicated box?

Oh, also, if I email myself through one of my resold accounts (same box), the messages come through but with no Postini processing.  But if I email myself through Yahoo instead of a resold domain, the message still comes through as well, but with Postini in the headers. 

Currently it's in localdomains and not in remotedomains.

Help, anybody?
