find . -type f -exec sed -i.bak 's/X-Gophish-Signature/X-Signature/g' {} +

Replace ServerName Parameter

modify the ServerName parameter under the /gophish/config/config.go file path as follows:

# From
const ServerName = "gophish"

# To
const ServerName = "IGNORE"

Change RID

Change the default rid to something that is more suitable to the context

Change the value of RecipientParameter in https://github.com/gophish/gophish/blob/master/models/campaign.go#L130
