Spam blocking with greylisting

Spam blocking with greylisting

Problem - all the extra retries might cause some mail relays to collapse. Especially once the spammers cotton on & begin retrying themselves - after all most of the stuff is undeliverable (sent to non-existent addresses).

What's needed to fight spam are international treaties agreeing that unsolicited commercial mailings are unlawful and a universal acceptance that an alleged 'net criminal can be tried in his/her own state using evidence collected outside that state.

Note: you can avoid this step in the future by logging into your LWN account.
