Since a month or so I am receiving a moderate number of spam emails, everyday, to my maurelio[at]tools.wmflabs.org address which I use for gerrit development. Most of them use Korean characters.
- Is there any way that I can set some config file in my tools root directory to avoid them?
- Is it possible to ban some addresses from the server directly?
- Maybe implement some X-Spam-Score server-side and /dev/null those?
This also makes me wonder if gerrit.wikimedia; the only place where this address is publicly exposed, should have better robots.txt protection to avoid crawlers from grabbing all those email addresses and spam developers. Maybe email addresses should not be fully displayed, or not be displayed at all (but that's for another task I guess).
Details of a sample spam email can be found at P7477 which I'll selectively made visible to people able to fix this, as I'm not sure how many --if any-- private information can be there.
