@paul.shf:
Hello paul.shf,
You can utilize the Keyword Blacklist to do this:
1. Start the ORF Administration Tool and connect to the local or remote ORF instance
2. Navigate to the Blacklists > Keyword Blacklist page
3. Click New
4. Select the "Header field: Subject" search scope
5. On the filter expression tab, enter the following regex expression (without the doublequotes): "^$"
6. Select the expression type "Regular expression (Pearl-compatible)"
7. Click Ok
Save the ORF configuration to apply the new settings (Ctrl + S).
If you need further assistance, just let me know.
Tell me how to block mail “without a subject”(No Subject)(Email Subject field is empty) using regular expressions?
Thank you.
