Step by step in Wix

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 Name
Leave this field empty
Priority
10
Points to
in1-smtp.messagingengine.com
Type
MX
Host Name
Leave this field empty
Priority
20
Points to
in2-smtp.messagingengine.com

In Wix

  1. Under MX (Mail exchange), select connect a business email.
  2. Choose Other from the drop-down list, then + Add record.
  3. Enter the mail server in Points to and the Priority. Host Name fills in automatically.
  4. Delete any other MX records listed, then select Save.
  5. 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
Leave this field empty
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 Wix

  1. Select + Add Record in the TXT (Text) row.
  2. Leave Host Name blank for your bare domain, enter the Value and a TTL.
  3. 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
Host Name
fm1._domainkey
Value
fm1.yourdomain.com.dkim.fmhosted.com
Type
CNAME
Host Name
fm2._domainkey
Value
fm2.yourdomain.com.dkim.fmhosted.com
Type
CNAME
Host Name
fm3._domainkey
Value
fm3.yourdomain.com.dkim.fmhosted.com

In Wix

  1. Select + Add Record in the CNAME (Aliases) row.
  2. Enter the Host Name and the Value.
  3. Select Save.
  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
Value
v=DMARC1; p=none;

In Wix

  1. Select + Add Record in the TXT (Text) row.
  2. Leave Host Name blank for your bare domain, enter the Value and a TTL.
  3. 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 Wix’s words.

We only read public DNS records. Nothing is stored.

Common mistakes with Fastmail on Wix

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.

Wix: Add SPF in the TXT row

Wix's DNS editor has a separate SPF row. Microsoft's Wix guide says to ignore it and add the SPF value in the TXT (Text) row instead.

Fastmail on Wix: questions

Where do I add Fastmail DNS records in Wix?

Sign in to Wix and select Domains in the left menu. Find your domain, select the three dots (...), then Manage DNS Records. Add each record there, one at a time.

What goes in the Host Name field at Wix?

Leave it empty 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. Wix adds your domain automatically.

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

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.
