Authorized senders (SPF)

SPF lists the servers allowed to send e-mails for zoom.us.

v=spf1 include:%{ir}.%{v}.%{d}.spf.has.pphosted.com include:_spf.google.com include:amazonses.com ip4:52.38.191.241 include:servers.mcsv.net include:_spf.salesforce.com ip4:13.110.78.0/24 ~all

E-mail signing (DKIM)

DKIM keys published by zoom.us 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 zoom.us arrive; SPF, DKIM and DMARC let mail servers check that an e-mail claiming to come from zoom.us was really sent by this domain, which protects it against spoofing.

zoom.us  MX  10 mx1.zoom.us.
zoom.us  MX  20 mx2.zoom.us.

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

google._domainkey.zoom.us  TXT  "v=DKIM1; k=rsa; p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA…"

_dmarc.zoom.us  TXT  "v=DMARC1; p=quarantine; rua=mailto:[email protected]; adkim=r; aspf=r"
