We’ve recently upgraded our email mapping function for Google Apps to automatically create SPF records.
This means that when we map a domain for Google Apps we:
- create the standard MX records needed to send/receive mail
- create the CNAMEs needed to access mail from subdomains (e.g. mail.yourdomain.com)
- create the SPF record to make it harder for spammers to send mail pretending to come from you
