When you send an email from f...@bar.com the mail server on the other
end can lookup the SPF record for the domain bar.com (this info is
part of the DNS records for bar.com). In a nutshell the SPF records
are used to determine whether the server sending mail from
someth...@bar.com is allowed to send mail on behalf of that domain.
Different mail servers receiving mail may be more or less stringent:
it could merely count towards a score that determines whether the
message is classed as spam or might lead to it being rejected
altogether.
