Incompletes email headers

[jlh1]

My email users received empty email (No from, to, subject or body information) several times a day. I have looked at the headers to try to determine how the email gets routed to the machine and more importantly how to set a filter to block these emails.

This is an exact header from one of these emails. I have “x” out my email server’s address and host name but I believe that the ip number in the brackets is from the real originating machine. Could some one explain how these emails are being delivered?

I run an Ipswitch ver 8.12 email server running in windows 2000 server with Outlook clients on the users workstations.

Thanks for the quick response.

That is the complete header from the email copied from Outlook .

The message id line is missing from the outlook header.

it appears that the person sending the emails is using a relay service:

Global SMTP Relay Server
Universal SMTP relay server. Send outgoing e-mail from any ISP. Ideal for travellers.

contact mailserver.com - give them the message id A38D12C60310 and ask that they look into this matter. also provide them the info in my previous post.

do me a favor and check one more thing.

if you still have any of the blank emails, right click in the preview pane and click on "Select All" and let me know if anything shows up.

thanks.

Sorry it took so long.

I did as you asked and nothing appeared, I tried to copy / paste the body of the email to a text document and nothing was there.

did you contact mailserver.com?
