3. In the DNS section, search for and delete all NS records for "_domainkey" pointing to Infomaniak.
4. Add a new TXT record for DKIM (it is not enough to paste the DKIM signature visible on the Infomaniak Manager for it to work):
   1. Type: TXT
   2. Name: Enter only the DKIM selector provided by Infomaniak (without "_domainkey" or the domain name), for example 20240112…
   3. Content : Paste the public DKIM key provided by Infomaniak (what comes after p=)
   4. TTL : Auto
5. Save the changes.
   • Any DNS addition/modification may take up to 48 hours to propagate.
6. Use an online DKIM verification tool to confirm the configuration.
