@kcit:
Hello kcit,
If you need to block something based on a specific header field or tag, you should add a wildcard or regular expression to the Keyword Blacklist of ORF with an "Email header (raw MIME)" search scope (ORF Administration Tool: Blacklists > Keyword Blacklist > New > Filter Properties > Search Scope).
Let me know if you need anything else.
Anything ORF can do for email bombs? Sites that sign you up for newsletters in bulk that then send you confirmation emails? We have one user who's received 2000+ emails in under 4 hours.
Since the emails are coming from valid sources the traditional tests don't work. I've read there are ways to block certain header tags if they are present. How can ORF deal with this?
