Missing emails

We have been receiving complaints about random missing emails. A user knows an email has been sent to them, and has received other emails from the sender (even perhaps a few minutes earlier), but some emails (mostly with attachments?) never arrive.

I check our spam filter and find nothing. There is also no record of the missing emails in the Message Tracking on our Exchange 2007 server, or in the Exchange queues.

If I put the sender's domain in our Positni spam white list, it doesn't seem to help. The sender also never gets a rejection or a return on the email they send.

Is there a possibility our server is "receiving" the emails but never processing them?

I'm at a loss in trying to figure out what is happening.

I would think it has something to do with either your spam filter or antivirus. It sounds as if they're never even reaching the Exchange box. Have you tried turning of the filter in its entirety for a test?

I would suspect it has something to do with postini.

Can you bypass them and get your mail directly for testing purposes and then if you receive the emails, you know the problem is with postini.  If not, then it sounds like an issue on your server with antivirus as suggested.

Have you checked with postini support? They track all messages and if they are dropping suspicious emails, they will probably not send a Non-Delivery report.

Threat Trends for MSPs to Watch

See the findings.
Despite its humble beginnings, phishing has come a long way since those first crudely constructed emails. Today, phishing sites can appear and disappear in the length of a coffee break, and it takes more than a little know-how to keep your clients secure.

The consensus seems to be that Postini is the problem. Is there a way to view what has gone through their system without contacting support?

MiniDevoCommented:
Not that I know of. I've always had to go through their support for that level of information.

Agree with minidevo. You will need to contact postini to get that info I suspect.

Can you bypass them and test mailflow?

It looks like it is Postini.
