Hi All,
We have exchange server 2013 on which McAfee Security for Exchange & Anti-Spam is installed. We have enabled the built-in Exchange anti-spam agents as well.
Lately we started receiving spam mails from the same domain but with fake accounts. We noticed that the source IP of the spam mail and the server is same.
All laptops & PCs are protected with anti-virus and up to date where mailboxes are configured.
How can we blocked the spam mails?
