How to block Senders that have a space in the "FROM" name
Hi everybody, since few day we've received spam in our exchange server.
those mails are not marked as SPAM.
The Name address of these mails look like this "arturmartin @ our domain name" (it's our domain name , and the From is random mail address from .ru .nl .cn ...
Is there a way in smtp proxy to block mail wtih a space in the sender name.
All rules that i've done with "from:" don't work.
Thank you for helping me
