Recently we started getting errors when trying to delete forwarders. For example:
Unable to locate the forwarder “waukesha@wordcamp.org” for account “example@gmail.com” on domain “gmail.com”.
We can still add them, though.
I tried manually edited /etc/valiases/wordcamp.org, but it just got overwritten a few minutes later with same contents it had before, so it seems like it’s not the canonical source for that data.
You can use the iandunntest2 forwarder for waukesha@wordcamp.org as a test.
