[tor-relays] Spam Emails Received From This Mailing List

Hello fellow relay operators,

My apologies as this is not related to tor relays, however, there seems to be several spammers subscribed to the relay list. Every time I am involved in a discussion on this list, I receive 3-5 emails supposedly from girls wanting to meet up (for sex). The emails in question claim they are sent from email address tor-relays@lists.torproject.org (and always have the same email subject of the discussion I was involved in).

I am somewhat in a trap as blocking them with spam filters would block all emails sent from the relay lists address. I am wondering what could be done about this (the email provider in question is Gmail).

Thank you.
