I'm mucking with an idea, and hoping the denizens here might have some input, esp. about potential breakage introduced. Summary: For any given valid recipient, compare the sender whitelist of exact matches and regexes. If the sender is NOT present, issue a permanant deny (5xx). Details: For the Gentoo mailing lists, we're seeing a lot non-subscriber traffic that just presently gets dumped to /dev/null (no list bounce saying you're not subscribed), and I would like to outright prevent that traffic. At the same time, this would enable legitimate users that just didn't have their subscription correct to get an error message (from their outbound mailserver). I'm wondering what breakage this idea is going to cause, esp. if there are some mailservers out there that might cache failures. -- Robin Hugh Johnson Gentoo Linux: Developer, Trustee & Infrastructure Lead E-Mail : robbat2@gentoo.org GnuPG FP : 11AC BA4F 4778 E3F6 E4ED F38E B27B 944E 3488 4E85Thread Next
