I have very little knowledge about spf records. I have Googled a little and found that spf records are used to prevent email spoofing. But I dont really understood how this works. I would like to know about the following things in brief.
How to set an spf record for my website. (Any links pointing to securely set an spf record may be useful)
Is there a significant difference between using
~. For example:
what is the difference between
TXT @ "v=spf1 a include:_spf.google.com ~all"
TXT @ "v=spf1 a include:_spf.google.com -all"
- Can spf records actually prevent attackers from spoofing my mail server.
Thanks in advance :)
