Fastmail + Wix

Set up Fastmail on Wix

The records Fastmail needs, written with the field names Wix uses (Host Name, Points to, Value), in the order to add them.

Before you start

  1. Have your Fastmail account ready. Some values are unique to your account and come from the Fastmail Settings .

Step by step in Wix

Point your MX records

MX records tell other mail servers where to deliver your email. How MX works

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

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 lists the services allowed to send email as you. How SPF works

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 signs your mail so receivers can trust it. How DKIM works

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 fakes your domain. How DMARC works

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. Sending servers pick an MX record by its priority (lowest number first) and fall back to the others, so a leftover MX record can receive some or all of your mail. 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.
