Spam attack on a client in the protected domain

[h_celik]

I have protected domains on fortimail. There is a heavy spamming of one user here. What kind of setting should I make?

Please try to re-add the picture because you have left domain in the first row. Cover that part too.
It depends what you want to do with those spam emails. Normal action is to block them.

I have configured the settings, but which setting should be used for such a succession of spam mails?

I think you can enable "Dictionary" and block e-mails with subject containing "Warning: message" or "delayed 48 hours"
