Enabling the antispam features isn't really going to help ---It didnt help
i checked "Ensure that you don't have externally secured enabled on any of the Receive Connectors.
" they were no marked
Normally my isp control mails from extern .They have spam filter for us. Last week they changed score to 12 then my internal relay Domain gets Spams.

Do your MX records point at the ISP? -yes smart host SMTP we use

our isp filter spam mails before come to us. My isp says I do not Need any Exchange Server
SPAM FILTER because disturb their Server . for that reasen I did Exchange Server Spam filter deactiveded .
They says it my internal Problem if accepted Domain is internal Relay Domain.

You need to look at the headers of the spam messages to see if they came via the ISP. If they did then you need to query with the ISP why so much is getting through.
 


I looked they are from External IP. (like .ru,ca etc)
I have a question. This a internal relay Domain(mydomain.de) but not standard.
we use other Domain (mydomain.com)for emails.

is this spam Problem (mydomain.de) Comes from my Exchange Server or from ISP ?
