Comment 8 for bug 1745512

As a last followup (for now), I did eventually manage to get the server delisted in Mailspike and set up a packet capture to log all E-mail exiting the server. With a few days it ended up listed in Mailspike again with "worst possible reputation" and the only messages which ever left the server were notifications about updated questions going out to people who had explicitly subscribed to the tags associated with those questions. I have to assume that someone has somehow managed to subscribed a Mailspike honeypot address or is reporting the notifications to Mailspike as spam, but either way I don't see any solution to this short of disabling E-mail notification for the server or clearing everyone's subscription preferences and asking them to re-subscribe to question tags all over again.
