After a pretty quiet time, the spam has started again. I have been alway managed to block but not sure how to deal with these Donny Leiden <firstname.lastname@example.org> and Julian Drenth <email@example.com> plus about twenty others. The domain names are always different now apart from .eu.
Specifically, see the thread 'Phishing' by MalcomP. Among other things, there is a link [Message 3 on the thread] to a Spam filter format to send all .eu e-mails to Spam folder. It helped me so I hope this helps.
