Hi all,
I'm currently trying to understand why I have 2 Zendesk netblocks in my SPF record. Both the
_netblock.zdsys.com
mail.zendesk.com
Netblocks are in my SPF record. _netblock.zdsys.com is a duplicate of the IPs in mail.zendesk.com. The latter has more IPs in the list. I'm wondering if removing the former will have any impacts to emails from zendesk? I wouldn't imagine it to be as the IPs are the ones you are allowing to send emails on your behalf, but would like someone's opinion on it.
Thanks for your help.
