E-mail DNS Settings for Third-Party Nameservers

This page is showing a generic answer.
To see a more detailed answer customized for you, type your domain name here:

This page lists the DNS settings that technically advanced customers can use if they run their DNS nameservers and website elsewhere, but still want Tiger Technologies to host their email.

Most customers do not need the information on this page. We normally handle DNS service for you, behind the scenes. This page is only for customers who are doing something unusual by having another organization handle their DNS service while we handle their email service.

Restrictions

If you do this, please note the following restrictions:

  • This method can be less reliable because it’s more complicated than letting us handle your DNS service. We describe it because some customers have no alternative, not because we think customers should usually split their mail from their DNS service.
  • We can’t handle your mail unless you have an active “hosting” account with us, because the “hosting” account package is what includes the email service. Don’t cancel your Tiger Technologies hosting service, even if you point the website elsewhere.
  • If you set things up this way when you first sign up with us, our system will still send you reminders asking you to point your nameservers at our company. You’ll have to contact us and ask us to turn those reminders off.
  • This page explains how to point email at Tiger Technologies mail servers. We have a separate page explaining how to point websites at our Web servers if you need it.

DNS entries to add

The “example.com” shown below is a generic example.

To see the exact DNS settings to use for your account, please enter the domain name of a website hosted by Tiger Technologies at the top of this page.

The DNS entries you should create at the other company are:

@                       MX 10  mx.tigertech.net.

@                       TXT    "v=spf1 include:customers.tigertech.net ?all"

1.tigertech._domainkey  CNAME  1.tigertech._domainkey.tigertech.net.
2.tigertech._domainkey  CNAME  2.tigertech._domainkey.tigertech.net.

lists                   CNAME  lists.example.com.customers.tigertech.net.
www.lists               CNAME  lists.example.com.customers.tigertech.net.

Technically speaking, only the first entry — the MX record — is necessary to make basic mail work. However, adding the TXT entry and the first two CNAME entries will reduce the possibility that recipients will reject outgoing mail sent through our servers, and adding the last two CNAME entries will also allow Mailman mailing lists to work.

If it’s not clear how to enter these DNS entries at the other company, you will need to contact them for assistance. Each company has their own procedure.

If I do this, how do I stop the messages asking me to update the DNS nameservers?

When you sign up for a new domain name with us, our system will automatically send you reminders asking you to update the DNS nameservers. If you follow the instructions above, you’ll keep getting those notices because our system won’t automatically know you’re doing something different. While they eventually get sent less often, you’ll still get them at least once a month.

To stop the notices, just contact us and send us this text:

As described on your “E-mail DNS Settings for Third-Party Nameservers” page, I am going to point only the email for example.com at your servers using an MX record. Please disable the reminders asking me to update the DNS nameservers.

We’ll adjust your account so you don’t receive any further reminders about updating the DNS.
