For all things to do with mailing lists and instrastructure I reach out to the system admin committee:
- The system admin committee issue tracker, you need an OSGeo id https://id.osgeo.org/ldap/create
- IRC freenode channel #osgeo-sac
- Instructions https://wiki.osgeo.org/wiki/IRC (tip you need to create a “nickname” with NickServ to type now)
- a chance to be personal, or for real emergencies
- The email list sac@lists.osgeo.org
- The system admin committee really likes the issue tracker, even when sending an email the first response is often to create an issue
