I have created a SPF record but am unsure if I need to create this for each domain or just the domain of the mail.myserver.ca
For example I have
I also have
Should I have each company create there own spf entry? Or as I understand it all thats needed is mail.server.com as that is my only MX server.
TXT myserver.ca 4 hrs v=spf1 a mx ip4:126.96.36.199 ip4:188.8.131.52 include:myserver.ca ~all
Record: v=spf1 a mx ip4:184.108.40.206 ip4:220.127.116.11 include:myserver.ca ~all
Prefix Type Value Prefix Desc Description
+ a Pass Match if IP has a DNS 'A' record in given domain
+ mx Pass Match if IP is one of the MX hosts for given domain name
+ ip4 18.104.22.168 Pass Match if IP is in the given range
+ ip4 22.214.171.124 Pass Match if IP is in the given range
+ include myserver.ca Pass The specified other domain is searched for an 'allow'.
~ all SoftFail Always matches. It goes at the end of your record.
126.96.36.199 is my mail.myserver.ca 188.8.131.52 is just where my website is hosted and has nothing to do with sending emails out of (I will probally remove that but got auto generated)
Questions, should include or any of the referances above be mail.myserver.ca?
