If emails notifications aren't being received, add enzoic.com to your approved senders. If your spam filter requires you to whitelist the Enzoic SMTP servers by IP address, you can determine the current IP address list with the following commands:


  • Windows:
    C:>nslookup -type=TXT amazonses.com | find "v=spf1"

  • Linux/OSX:
    $ dig TXT amazonses.com +short| grep 'v=spf1'


  • This will return the SPF record in use, which will change over time. Example:
    "v=spf1 ip4:199.255.192.0/22 ip4:199.127.232.0/22 ip4:54.240.0.0/18 ~all"
