Route 53 DNS
Route 53 wants TXT values wrapped in quotes and MX priority inline in the value box. Publish Mailfully's records to match.
Route 53 has two quirks that catch out anyone copying values straight across from another host: a TXT value has to be quoted, and an MX value carries its priority as a number in front of the target rather than in a field of its own. Get those two wrong and the record looks saved but never resolves the way verification expects.
Open Hosted zones, select the zone for acme.com, and use Create record for each value Mailfully returned.
Add the records
Add a record for each DKIM token:
| Field | Value |
|---|---|
| Record name | <token>._domainkey.mail |
| Record type | CNAME |
| Value | <token>.dkim.mailfully.com |
| TTL | 300 |
The Record name box is relative to the hosted zone, and the console prints the zone name beside it so you can see the full name it will save. Do this for all three tokens.
| Field | Value |
|---|---|
| Record name | send.mail |
| Record type | MX |
| Value | 10 feedback-smtp.us-east-1.amazonses.com |
| TTL | 300 |
| Field | Value |
|---|---|
| Record name | send.mail |
| Record type | TXT |
| Value | "v=spf1 include:_spf.mailfully.com ~all" |
| TTL | 300 |
| Field | Value |
|---|---|
| Record name | _dmarc.mail |
| Record type | TXT |
| Value | "v=DMARC1; p=none;" |
| TTL | 300 |
Quoting and priority
A Route 53 TXT value is a quoted string, and the quotes are saved with it. Enter the value on one line, with its quotes: "v=spf1 include:_spf.mailfully.com ~all". Each line in the Value box is a separate value.
MX has no separate priority field. The number Mailfully returned, 10, goes in the value box ahead of the target host, separated by a single space: 10 feedback-smtp.us-east-1.amazonses.com.
Verify
dig +short <token>._domainkey.mail.acme.com CNAME
dig +short send.mail.acme.com MX
dig +short send.mail.acme.com TXT
dig +short _dmarc.mail.acme.com TXTVerify with dig has the expected answer for each lookup.
