I don't think I changed any config on my part, but mail from my commits to cmucl now seem to be coming from gitlab@common-list.net instead of from rtoy@common-lisp.net. So now the message are all getting held, waiting for approval because that's not a member of the list.
Also, maybe I can remove my post-receive git hooks now? Can gitlab be configured to send out messages the cmucl commit list?
