Step by step in Bluehost

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
Host Record
@
Priority
10
Points to
in1-smtp.messagingengine.com
Type
MX
Host Record
@
Priority
20
Points to
in2-smtp.messagingengine.com

In Bluehost

  1. Under the DNS tab, go to Manage Advanced DNS Records and click Add Record.
  2. Set Type to MX. Type @ in Host Record, enter the mail server in Points to, and set the Priority. Leave TTL at its default.
  3. Save the record.
  4. 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
Host Name
@
TXT 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 Bluehost

  1. On the DNS tab, click + Add Record and select Single Record.
  2. Set Record Type to TXT and Refers to to Other Host.
  3. Enter the Host Name and paste the TXT Value.
  4. Click Add.

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
Host Record
fm1._domainkey
Points to
fm1.yourdomain.com.dkim.fmhosted.com
Type
CNAME
Host Record
fm2._domainkey
Points to
fm2.yourdomain.com.dkim.fmhosted.com
Type
CNAME
Host Record
fm3._domainkey
Points to
fm3.yourdomain.com.dkim.fmhosted.com

In Bluehost

  1. Under the DNS tab, click Add Record.
  2. Set Type to CNAME, enter the name, and put the target hostname in Points to.
  3. Save the record.
  4. 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
Host Name
_dmarc
TXT Value
v=DMARC1; p=none;

In Bluehost

  1. On the DNS tab, click + Add Record and select Single Record.
  2. Set Record Type to TXT and Refers to to Other Host.
  3. Enter the Host Name and paste the TXT Value.
  4. Click Add.

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 Bluehost’s words.

We only read public DNS records. Nothing is stored.

Common mistakes with Fastmail on Bluehost

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.

Bluehost: Replace Bluehost's default MX record

By default Bluehost's MX record points to your own domain, which delivers mail to Bluehost's local server. Change it to your provider's mail server.

Fastmail on Bluehost: questions

Where do I add Fastmail DNS records in Bluehost?

Log in to the Bluehost Portal and click Domains in the left-hand menu. Select your domain, then open the DNS tab. Add each record there, one at a time.

What goes in the Host Record field at Bluehost?

Enter @ for records on your bare domain, such as MX and SPF. For the others, enter fm1._domainkey.

Do I need to delete my existing MX records at Bluehost?

Yes. Mail servers deliver to every MX record you publish, so keep only the Fastmail MX records and delete the rest. By default Bluehost's MX record points to your own domain, which delivers mail to Bluehost's local server. Change it to your provider's mail server.

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.
