Set up your DNS at Namecheap
Step-by-step DNS setup for Namecheap. New to this? Start with the DNS setup overview to understand Full DNS vs Split DNS and pick the right option — then follow the matching section below. Examples use example.com; copy the real values from the cripta.to setup screen.
Change your nameservers
Repoint Namecheap's nameservers to the two cripta.to shows you — cripta.to then manages every record for you. What does this mean?
- Sign in to Namecheap and open Domain List.
- Click Manage next to your domain.
- Find the Nameservers section on the Domain tab.
- Change the dropdown from “Namecheap BasicDNS” to “Custom DNS”.
- Enter the two nameservers cripta.to shows you (add a row for the second one).
- Click the green checkmark to save.
Add the records at Namecheap
Keep Namecheap as your DNS host and add the records below yourself. What does this mean?
How to add a record at Namecheap
- Sign in to Namecheap and open Domain List.
- Click Manage next to your domain, then open the Advanced DNS tab.
- In the Host Records section, click Add New Record.
- Choose the record Type, fill in the fields, and click the green checkmark to save.
- For the MX record, first set Mail Settings (above Host Records) to “Custom MX”.
1 · Delegate the mail subdomain (NS)
Add an NS record for each nameserver cripta.to shows you, all on the host mail. This hands the mail.example.com subdomain to cripta.to so it can manage the server's own records (like its A record and TLS) without touching the rest of your domain.
| Type | Host | Value |
|---|---|---|
NS | mail | the nameservers cripta.to shows you (one NS record each) |
2 · Add the root-domain mail records
| Type | Host | Value | Notes |
|---|---|---|---|
MX | @ | mail.example.com | Priority 10 — routes incoming mail to your server. |
TXT | @ | v=spf1 mx ~all | SPF — authorizes your server to send mail. |
TXT | _dmarc | v=DMARC1; p=none; rua=mailto:d4d8f72c1a3b5e70@dmarc.cripta.to | DMARC policy. |
TXT | mail._domainkey | v=DKIM1; k=rsa; p=… | DKIM — paste the full key cripta.to shows you. |
A | webmail | 203.0.113.10 | Webmail UI — use the exact server IP cripta.to shows you. |
The webmail A record is only needed if you enabled webmail. The mail server's own A record is handled by cripta.to through the NS delegation above — you do not add it here.
3 · Add the SRV autodiscovery records
SRV records let mail apps (especially Android and Thunderbird) find your IMAP and submission servers automatically. Namecheap splits an SRV record into separate fields — enter them exactly as shown. Add both records below.
- Type
SRV Record- Host
_imaps._tcp- Priority
0- Weight
1- Port
993- Target
mail.example.com- TTL
Automatic
- Type
SRV Record- Host
_submissions._tcp- Priority
0- Weight
1- Port
465- Target
mail.example.com- TTL
Automatic
If your Namecheap panel shows a single combined value field for SRV instead of separate boxes, enter it as “0 1 993 mail.example.com” (priority weight port target). Replace example.com with your own domain.
After you save, DNS changes usually take 5–30 minutes (up to 48 hours) to propagate. cripta.to detects the change automatically and continues onboarding — you can close the setup page and come back later.
