E-mail signing (DKIM)

DKIM keys published by ringcentral.com under the most common selectors. Other keys may exist under selectors specific to each sending service.

RSA keys shorter than 2048 bits, called short keys, are discouraged: they are easier to break.

MX, SPF, DKIM and DMARC: the e-mail records

Four DNS records make a domain's e-mail work. MX says where e-mails sent to ringcentral.com arrive; SPF, DKIM and DMARC let mail servers check that an e-mail claiming to come from ringcentral.com was really sent by this domain, which protects it against spoofing.

ringcentral.com  MX  10 mx1.ringcentral.com.
ringcentral.com  MX  20 mx2.ringcentral.com.

ringcentral.com  TXT  "v=spf1 mx include:_spf.google.com ip4:192.0.2.10 -all"

google._domainkey.ringcentral.com  TXT  "v=DKIM1; k=rsa; p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA…"
