Mail not being received

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.

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?

It is happening for several different people from different domains. As far as I know they are not getting any NDR messages. one was from a netscape.com email, others are from private domains, one was from Rogers.com. All the addresses in question are also on the senders whitelist in GFI.

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 www.mxtoolbox.com/diagnostic.aspx 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?

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

You had not mentioned that you had ISA server - which would have been useful to know and may have resulted in an earlier resolution.
