Some emails from a particular domain are not delivered to Postini therefore not reaching our Exchange SMTP servers
Posted on 2012-03-13
We use Postini as the spam filter solution. Emails are being delivered there and then once they are clean they are sent over to our Exchange servers.
We have found that some emails don't seem to be reaching our Exchange servers. We have checked Postini and seen that those emails are not reaching there either. If the emails are not reaching Postini they will not get delivered to Exchange.
I have called Postini but I am still waiting to hear from them. I was wondering if someone could help me out to verify that the problem is not in my end.
