Multiple SPF records
The below instructions will show you how to merge your SPF records on your domain name, so you don't have to use multiple records.
Multiple SPF records are not recommended.
Therefore, before adding an SPF record please check if there is already one setup for your domain. If there is an SPF record setup for your domain, you can merge the original record and the new one you wish to setup.
For example, if you have the below record for your domain:
v=spf1 include:_spf.google.com ~all
and you need to add:
v=spf1 mx a ip4:126.96.36.199 a:mailex.mailcore.me -all
The two SPF records can be merged into this one:
v=spf1 mx a ip4:188.8.131.52 a:mailex.mailcore.me v=spf1 include:_spf.google.com ~ all
So, the original record, v=spf1 include:_spf.google.com ~all, will need to be replaced with this one v=spf1 mx a ip4:184.108.40.206 a:mailex.mailcore.me v=spf1 include:_spf.google.com ~ all
The newly created SPF record sets a policy for your domain, telling mail servers across the Internet that emails sent from the addresses associated with your domain should only be accepted if these have been relayed using the 123 Reg and Google mail servers.
Please note: If you are using 123 email, then you should use the following SPF record: v=spf1 mx a ip4:220.127.116.11 a:mailex.mailcore.me -all.
