Some lowlife is sending spam emails with spoofed @niryariv.net sender address. This is pretty embarassing and frustrating – apparently there’s nothing to do about this, it’s exploiting a vulenrability in SMTP protocol that enables email to be sent with any sender domain in “From:”.
If anyone knows of any solution, please let me know. Meanwhile, I hope most everyone by now has spam filters strong enough to block these mails. My sincere apologies to anyone who’s getting these mails.
