DNS record setup for StartMail
Last modified on 17 May 2016 06:00 PM

You need to update the Domain Name Service (DNS) records of your domain in order to use StartMail. You have to configure this in the management console of your domain host, not in the StartMail Business menu.

Every domain host can use a slightly varying way to manage DNS records, so we can only provide general information about how to set it up. Ask for assistance at your host if you do not know how to manage your DNS settings.

To receive and send mail using StartMail you'll have to add or replace three additional records.

  • MX records specify where the incoming mail gets delivered to. To receive your mail at StartMail, you need to specify our servers here. It is important to correctly configure the priority to make sure that your email can be delivered to you reliably.
  • SPF records identify which mail servers are permitted to send email on behalf of your domain. The purpose of an SPF record is to catch spammers sending messages with forged From addresses at your domain. Recipients can refer to the SPF record to determine whether a message purporting to be from your domain comes from an authorized mail server.
  • DKIM records allow recipient servers to verify that the message really comes from your domain and hasn't been changed along the way.  

IMPORTANT!

Some DNS services provide special Record Types for SPF and DKIM. As those are not recognised by all servers, those should not be used.

Setting up the DNS Records

If you are setting up a subdomain, please consult [subdomain setup page]

a. Log in to your domain management panel from your host.

b. Locate the DNS settings page

c. Update all the MX records to match the following list, delete or create new entries as needed:

Record Type Name Value Priority TTL
MX yourdomain.com. mx1.smtp.startmail.com 10 600
MX yourdomain.com. mx2.smtp.startmail.com 10 600
MX yourdomain.com. smx-5c0.smtp.startmail.com 20 600

d. If there are any SPF records (type SPF or type TXT starting with v=spf1) remove them. Once done, add a TXT record with these values:

Record Type Name Value TTL
TXT yourdomain.com. v=spf1 include:spf.startmail.com ~all 600

Do NOT use an SPF record, which is no longer used. It has to be a TXT record.

e. If there is a DKIM record (one having _domainkey in its name), remove it. Once done, add a CNAME record with these values:

Record Type Name Value TTL
CNAME dkim._domainkey hosted.dkim.startmail.com 600

f. Save your changes

g. Go to your Business menu, submenu Domains, verify [yourdomain] and click on “Check DNS records”.

If you have configured all your settings correctly, they will turn green. If we found any incorrect information we display why the settings are incorrect and what we’ve found in the DNS records.

If you have changed your settings at your host, but StartMail does not recognize the latest change, this could well have to do with the response time of your domain host. Please contact support@startmail.com if this problem persists.

Note:

It might take up to 72 hours for all these changes to propagate across to all mail servers across the Internet. In the meantime emails could be bounced back to the sender or mail may be delivered to your old email provider. Usually the downtime is much shorter.
