mail authentication for wordpress

mail authentication for wordpress

Only one (the Super Administrator) of the five zoho mails is able to receive emails from wordpress, We managed to do this using the SPF verification code
v=spf1 include:spf.easywp.com include:zoho.com ~all
do i need to add a new record for each email in order for it to receive mails from wordpress?
if so, will that not cause duplication/conflict with the first TXT record?
