    The BackupMX service has given me and the company peace of mind knowing that our emails will get backed up even when something happens to our mail server. Bob Wilson, Milton Keynes, Bucks

Spam protection

Backup MX is not an anti-spam service.  If you are looking for an anti-spam service then try profilter.

Backup MX does however perform simple email checking to help prevent spammers from using our email servers to propagate spam to your mail server.

Backup MX checks the following:

  • reverse DNS is configured correctly on the sending mail server
  • Email address validation
  • Email header validation
  • Greylisting enabled
  • RBL checks enabled
