Security email listed in README doesn't work

[syvb]

The README says

If you believe you've found a security-related issue with Penumbra, please disclose responsibly by contacting the Penumbra Labs team at [email protected].

I sent an email there; I got this automated response:

We're writing to let you know that the group you tried to contact (security) may not exist, or you may not have permission to post messages to the group. A few more details on why you weren't able to post:

• You might have spelled or formatted the group name incorrectly.
• The owner of the group may have removed this group.
• You may need to join the group before receiving permission to post.
• This group may not be open to posting.

If you have questions related to this or any other Google Group, visit the Help Center at https://support.google.com/a/penumbralabs.xyz/bin/topic.py?topic=25838.

Thanks,

Thank you for reporting this. We'd only tested that alias with internal email addresses, which isn't sufficient. We've updated the settings now, and I can confirm receipt from external senders. Please retry sending your message to [email protected], and reopen this issue if you have any trouble, @syvb.
