The SPF is to reduce the possibility of spoofing by publishing in the DNS a record (of type TXT) indicating which IP addresses are allowed or prohibited to send mail for the domain concerned (depending on the geographical area).

The value to include is :

France / Europe: include:spf-eu.letsignit.com

Canada: include:spf-ca.letsignit.com

USA: include:spf-us.letsignit.com

Below is an example SPF record where the value is inserted between v=spf1 (beginning of SPF field) and ~all (end of SPF field), the SPF record is type TXT:

v=spf1 include:spfcloud.letsignit.com ~all

BE CAREFUL :

  • If no SPF value exists for your domain, make sure that no other third-party service sends emails on your behalf before creating a SPF to declare Letsignit.

  • If an SPF record is already present for your domain, add it after the other records (separated by a space).

Remember to check the number of records in your SPF record. (Maximum limit of 10 records).
