Just wondering what's your take with Postini mail filtering services. I was expecting a huge difference but even with the filter sensativity at max threshhold *5*,, 15-30+ spam emails still seem to trickle in. The built in *junk filter* in Outlook always seems to catch the stuff that get's past by the Postini filters.
Just wondering for those using Postini, how do you feel about the accuracy of the spam filtering services.
My webhost says that I can enable "spam assassin" on my email account for free. But if I want "Postini", then I will have to pay extra. I need spam protection on my email account. But I don't want any false positives because I don't even bother scanning through my spam box.
How much better is Postini than spam assassin? I know Google is trying to buy Postini. So I figure it must be pretty good. But is it so much better than than free one?
I've got a domain name ("problemdomain.com") on my server (CentOS 4, WHM/cPanel) that has been set up with Postini for quite some time. All has been working & routing correctly. I recently changed to a new server with a new IP address. I transferred the account so that the DNS is setup identically on the new server. The only thing that changed is the main server IP, and the IP addresses that ns1.myserver.com and ns2.myserver.com resolve to. That propagation went through today and should be well set in.
Now, whenever you send an email to someone on this domain, it gets bounced back with the following:
This is an automatically generated Delivery Status Notification
Delivery to the following recipient failed permanently:
mail@problemdomain.com
Technical details of permanent failure:
PERM_FAILURE: SMTP Error (state 13): 550-exprod8mx214.postini.com (psmtp.com) [64.18.3.114] is currently not
550-permitted to relay through this server. Perhaps you have not logged into
550-the pop/imap server in the last 30 minutes or do not have SMTP
550 Authentication turned on in your email client.
The way I have the DNS setup on the server for the MX records is as follows:
problemdomain.com., 14400, IN MX, 100, laserskinsurgery.com.s8a1.psmtp.com.
problemdomain.com., 14400, IN MX, 200, laserskinsurgery.com.s8a2.psmtp.com.
problemdomain.com., 14400, IN MX, 300, laserskinsurgery.com.s8b1.psmtp.com.
problemdomain.com., 14400, IN MX, 400, laserskinsurgery.com.s8b2.psmtp.com.
This DNS is exactly the way it was setup before when it was working. Any ideas what could be causing this?
I've got a PHP mail system which sends emails with these headers: ....
View 1 Replies View RelatedHas anyone done any comparisons between these companies.
I've tried reaching out to each and plan to do follow-ups .
3 calls, 2 phone convos with Postini and the local rep still has not called me back to discuss their offerings.
we've been evaluating the Postini product for a short bit and was hoping this would be all that it's touted for.
So far, we're seeing it catch about 60% of spam but still some very obvious blatent ones are coming in.
Amazingly, we have done a forward as well to a gmail account, the gmails junk filters are pretty damm good...it catches the *rest* that Postini does not tag.
Just curious if anyone has has used other 3rd party spam services and your feedback/review
