Stop your mail going to spam

Three DNS records decide whether your mail is trusted. All three are set for you when mail is hosted here.

## SPF

Lists the servers allowed to send for your domain. One SPF record per domain, no more.

## DKIM

Signs each message so the receiver can tell it was not altered. The key is published as a TXT record.

## DMARC

Tells receivers what to do when SPF and DKIM do not line up. Start at `p=none`, read the reports for a fortnight, then tighten it.

## If you send through something else

A newsletter tool or a shop sending on your behalf has to be added to SPF and given its own DKIM key, or its mail will be treated as a forgery.
