You need to read up on what SPF is, but it's basically a mechanism for restricting who can send mail on behalf of a domain. It's implemented as a list of IP addresses, in a DNS record, that are valid as sources of mail for that domain. Clearly your IP address is not in that list for the domain you are claiming your email is from. How to fix it? Make sure your outgoing mail is configured correctly. Your mail provider (ISP, company IT etc.) will be able to give you the correct server information you should use. If it is correct, then they have misconfigured their SPF entry. Unless you are the DNS/mail admin, then there's nothing you can do and you need to talk to them about it.
