Mail not being received

Posted on 2010-09-14

Hi All,

We seem to be having issues with receiving emails to our exchange server.  We are getting most email but there seems to be a lot that just never make it to our exchange server or inboxes.

We are running Windows server 2003 with Exchange 2003.  We have GFI Ver.14.1.  When I check the dashboard for GFI there is no sign of the missing emails.  Also when I check the message tracking in Exchange there is no sign of the email.
all the email addresses are on the whitelist in GFI so they shouldn't be getting blocked from there.

I am totally baffled as to why we would not be receiving these emails.  Any suggestions or help would be greatly appreciated.

have you checked gfi mail logs to see if anything has been bounced back due to size or encryptioln ?

I have only looked on the dashboard.  Would it not show it on the dashboard?  If not where would i check that?

Thanks for getting back to me.

Do you know if this is from a specific domain or just a specific user within a domain? Does the user that is trying to send you email get a NDR error message?

If the mail is not hitting GFI or your Exchange server then it is not getting to you, or being filtered before it gets to GFI.

Please check your domain on and check to see if your MX record is pointing to where you think it should be pointing.

Do you use a 3rd party spam service or does mail arrive directly to your server?

Hi Alan,

We are not going through any 3rd party spam filter.
I went to that site and ran it.  It all came back ok as far as I can tell.

So it turns out it was a rule on the ISA that was blocking the mail from coming in.  THanks for the help everyone.

"If the mail is not hitting GFI or your Exchange server then it is not getting to you, or being filtered before it gets to GFI."
You had not mentioned that you had ISA server - which would have been useful to know and may have resulted in an earlier resolution.
