Step by step in GoDaddy
Point your MX records
MX records tell every other mail server where to deliver email for your domain. They must point to your provider and nowhere else.
- Type
- MX
- Name
-
@ - Priority
- 10
- Value
-
in1-smtp.messagingengine.com
- Type
- MX
- Name
-
@ - Priority
- 20
- Value
-
in2-smtp.messagingengine.com
In GoDaddy
- Under DNS Records, select Add New Record.
- Choose MX as the type.
- Fill in Name, Priority and Value, and pick the TTL from the drop-down list.
- Select Save.
- Repeat for each MX record above.
Add the SPF record
SPF is a TXT record that lists the services allowed to send email from your domain, so receivers can spot forgeries.
- Type
- TXT
- Name
-
@ - Value
-
v=spf1 include:spf.messagingengine.com ?all
- This is the exact value from Fastmail's manual DNS guide, which ends in ?all (neutral).
In GoDaddy
- Under DNS Records, select Add New Record.
- Choose TXT as the type.
- Fill in Name and Value, and pick the TTL from the drop-down list. Copy and paste the value so the spacing stays exact.
- Select Save.
Set up DKIM
DKIM publishes a public key so receivers can confirm your messages really came from you and were not changed on the way.
- Type
- CNAME
- Name
-
fm1._domainkey - Value
-
fm1.yourdomain.com.dkim.fmhosted.com
- Type
- CNAME
- Name
-
fm2._domainkey - Value
-
fm2.yourdomain.com.dkim.fmhosted.com
- Type
- CNAME
- Name
-
fm3._domainkey - Value
-
fm3.yourdomain.com.dkim.fmhosted.com
In GoDaddy
- Under DNS Records, select Add New Record.
- Choose CNAME as the type.
- Fill in Name and Value, and pick the TTL from the drop-down list.
- Select Save.
- Repeat for each CNAME record above.
Add the DMARC record (recommended)
DMARC tells receivers what to do with mail that fails SPF and DKIM, and where to send reports about it.
- Type
- TXT
- Name
-
_dmarc - Value
-
v=DMARC1; p=none;
In GoDaddy
- Under DNS Records, select Add New Record.
- Choose TXT as the type.
- Fill in Name and Value, and pick the TTL from the drop-down list. Copy and paste the value so the spacing stays exact.
- Select Save.
Check your setup
Once the records are saved, run a live check. We look up your domain in public DNS and tell you what is right, missing or wrong, with the fix in GoDaddy’s words.
Common mistakes with Fastmail on GoDaddy
Adding fewer than three DKIM records
Fastmail signs with three selectors (fm1, fm2, fm3). All three CNAMEs are required.
Adding a second SPF record
Only one record may start with v=spf1. Merge Fastmail's include into the existing one.
GoDaddy: Type only the part before your domain
GoDaddy adds your domain to the Name automatically. Enter _dmarc or google._domainkey, not _dmarc.yourdomain.com, or the record ends up at a doubled name.

Fastmail on GoDaddy: questions
Where do I add Fastmail DNS records in GoDaddy?
Sign in to GoDaddy and open My Products. Under Domains, open the Portfolio tab. Select the three dots (...) next to your domain, then Edit DNS. Add each record there, one at a time.
What goes in the Name field at GoDaddy?
Enter @ for records on your bare domain, such as MX and SPF. For the others, enter only the part before your domain, for example fm1._domainkey. GoDaddy adds your domain automatically.
Do I need to delete my existing MX records at GoDaddy?
Yes. Mail servers deliver to every MX record you publish, so keep only the Fastmail MX records and delete the rest.
Where do I get my Fastmail DKIM record?
Fastmail DKIM records are CNAME records whose value includes your domain, for example fm1.yourdomain.com.dkim.fmhosted.com. Copy the exact values for your domain from the table on this page.
