I have to use GitHub for $reasons and Copilot decided to make some sub-agents with my username, which it prefixed references to with @. Naturally, this lead to an astronomical amount of spam.

For those in a similar situation and running Postfix, you may find this useful in your header_checks file

/^From: Copilot <notifications@github.com>/ REJECT I don't use copilot

#copilot #LLM #Postfix
