Authentification / SPF record


Previously, in Manage Client Name > Email Authentication Settings > Authenticate a new domain I had 2 fields: Sender ID & DKIM.

Sender ID was a TXT record to add, like "v=spf1 a mx ?all".

Is it correct that we only have a record for the DKIM to insert in DNS (I haven't seen any announcement for it).

Do we maintain the existing SPF records?

Thx in advance for your answer.
