Ask HN: Anyone from Facebook infra/email around?

1 pointemilburzo0 comments

It seems that Page notification emails do not have any signature data (DKIM), while regular notifications do.

This, coupled with strict DMARC email policy (reject) means I cannot receive those emails.

Straight from the email logs:

# Pages

    2CA922BC00EE: 66-220-155-162.outcampmail.facebook.com [66.220.155.162] not internal
    2CA922BC00EE: not authenticated
    2CA922BC00EE: no signature data

# Regular

    46E8B2BC08FD: 66-220-155-157.outmail.facebook.com [66.220.155.157] not internal
    46E8B2BC08FD: not authenticated
    46E8B2BC08FD: DKIM verification successful
    46E8B2BC08FD: s=s1024-2013-q3 d=facebookmail.com SSL

I've tried going through the regular channels, but no response.

Is anyone else seeing this or is something really wrong with my setup?
