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.

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 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.

autoconfig              CNAME  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, adding the “lists” CNAME entry will allow Mailman mailing lists to work, and adding the “autoconfig” entry allows the Thunderbird and Outlook mail programs to simplify adding an address.

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.
