Domain DNS Setup

Required DNS records

To send email from your domain via Venmail, configure these DNS records:

1. SPF Record

   Add a TXT record on your root domain:

   v=spf1 a mx include:spf.venmail.io ~all

2. DKIM Record

   Add a TXT record on venmail._domainkey.yourdomain.com:

   v=DKIM1; t=s; h=sha256; p=MIGfMA0GCSqGSIb3DQEB...

   The exact value is shown in your Venmail dashboard after adding the domain.

3. Return Path (CNAME)

   Add a CNAME record on rp.yourdomain.com:

   rp.yourdomain.com CNAME rp.venmail.io

4. MX Record (for receiving)

   If you want to receive mail through Venmail, add MX records:

   yourdomain.com MX 10 mx1.venmail.io
   yourdomain.com MX 20 mx2.venmail.io

VVS-1 DNS Record (optional)

To publish VVS-1 agent keys via DNS, add a TXT record on _venmail.yourdomain.com:

v=VVS1; agent=billing; pubkey=MCowBQYDK2VwAyEA...; kv=1; status=active

See VVS-1 Key Management for details.

Tip

DNS changes can take up to 48 hours to propagate, though most providers update within minutes. Use dig or an online DNS checker to verify.

Verification

After adding DNS records, verify them in the Venmail dashboard or via the Domains API. All four checks (SPF, DKIM, Return Path, MX) should show “OK” status.
