Normally, for all our hosted domains, the SPF records that we send out did not have the 'reject' option therefore anyone in the world could claim to send emails from YOUR domain. For example, someone in another country could have sent mails from your domains, pretending to be you!
However starting today we are tightening our SPF records for more security. That means if someone sends mail from ANOTHER system pretending to be you, the receiving mail servers (the ones that support SPF, which is most of them) would reject their mail(s)..
If you ALSO send mail from another host, say, a bulk mailing company for example, you may need to make changes to your DNS records accordingly using our PLESK control panel.
