We are trying to understand all of these because we will be required to use them eventually.
I am getting my info at https://www.dmarcanalyzer.com/spf/ If we add an IP to our SPF record, is any additional action necessary for the DMARC and/or DKIM records ? The site says, " When using SPF you need to take note of a limitation in this technique. The number of DNS lookups which are allowed to take place is limited to 10." If we have more than 10 email senders, are we SOL or is there a way to include them without breaking this rule ? Multiple SPF records ? Thanks in advance. Responses to previous questions have been extremely helpful.
