It seems that it is completely impossible to block emails based on subject line or message body, if EOP has already classified the messages as Junk.
So my Junk Email folder is filled with the same CANADA PHARMACY and USA PHARMACY stuff, about 10 a day, which I could very easily block, if only the system would let me.
Outlook rules do not run against the Junk Email folder, Exchange Mail Flow rules do not work, and the new Defender for 365 security portal does not have any options for subject or message body.
Is this ever going to improve? Why do the mail flow rules not work once the message has been classified as Junk by the edge filters?
Not sure I understand your question.
Mail Flow rules are applied before anti-spam in EOP:

You can use those to block by subject
Hi Andy.
It doesn't work. It works when I test myself, but all..
Oh, wait.. You are right.
I feel a bit stupid, but still stuck with this annoying spammer.
It's actually the sender's name that I want to block. The senders name is so prominent in the message list that the subject is almost irrelevant. I did hope that 'subject or body' would cover it but it doesn't.
I'll see if this works:
Ok, in that case you can block within Outlook or a mail flow rule as well based on sender:
The sender address changes every time as they are using hacked websites for both sending the emails, and hosting redirect pages.
but they use a consistent sender name.
It seems the 'message header includes' -> 'header: from' -> 'USA PHARMACY', 'CANADA PHARMACY' covers it.
Thanks for your help. This spam has been frustrating me for a long time.
Outlook rules don't work against Junk Email. You can run them manually, but they don't run as messages arrive. Also these are being put in my junk folder by EOP rather than Outlook.
Ok, cool!. Please mark an answer as accepted if you dont mind so this thread can be closed. Thanks!
