Why is this notification sent from an email address that appears to be for another site on the network?
For the reasons outlined by Nick Craver in comments to the question, we will not change the from address of the email, namely:
- it is not a simple change, as some people think
- it will make it difficult to whitelist all SE emails
We have updated the subject line of the emails to include the community name - so this should alleviate such concerns in the future.
