Asked by Stephen Meehan
Hi,
I have two websites, on two different Droplets (with different IP addresses)
Both websites use the same domain, the first website is mysite.com and second website is example.mysite.com
I need to edit my SPF record so it can allow both IP Addresses to to use the domain mysite.com
When I use the correct IP Address the SPF record below works (for one of the websites).
v=spf1 ip4:167.XX.XXX.40 include:spf.protection.outlook.com -all
Let’s say one droplet IP address is: 167.XX.XXX.40 and the other IP address is 167.XX.XXX.247
How would I add both to the same SPF record?

v=spf1 +a +mx ip4:167.XX.XXX.247 ip4:167.XX.XXX.40 include:spf.protection.outlook.com ~allv=spf1 a -all From everything I read, that should allow every IP listed in your A records to send mail. But, so far it’s not working for me.
Recipient address rejected: Message rejected due to: SPF fail - not authorized
(a) or (+a) seem to be the same thing, (a) just defaults to (+a)
You can enter the IP manually like shown in other answers, but it seems like (a) should have worked if both your servers have A records. Perhaps mine isn’t working because it needs to propagate. :(
Hi Jason,
Thanks for the reply.
After a bit of searching I found this , it looks like this would also work:
v=spf1 ip4:167.XX.XXX.247 ip4:167.XX.XXX.40 include:spf.protection.outlook.com ~allThe
aand themxmechanisms default to+, so I guess there’s no need to specify them as such.
