Purpose

The purpose of this  article is to define a consistent and understandable configuration for the client  when setting up their Domain Name  Records for either sending on dedicated or shared IP addresses or using a relay partner such as Mailgun or Mailchimps SMTP relay.  It  is  broken down into 2 parts, for that reason.

Basic

When a client sends an email broadcast on our  system  we configure things in such a way that replies, postmaster and abuse requests go directly back to the client, but daemon level activity and information that needs to come directly back to us  so that we can manage the broadcast (bounces, daemon-mail, complaints, feedback loop  responses) come back to us so that we can sort it and present it to you  and adjust the broadcast accordingly and update your sending behavior.  

This is magically accomplished through DNS configuration.  We need you to either make the following configuration changes or delegate the subdomain mom.<your fqdn> to us.  Open a ticket with our support group telling  them

Configuration Required for Sending on Dedicated  or Shared IPs

Please add these DNS records to your domain's "zone" file:

mom                     IN TXT           "v=spf1  include:_spf.mmailer.net ~all"
mom                     IN MX       10   vbounces.mmailer.net.
default._domainkey.mom  IN CNAME         _em._domainkey.mmailer.net.            
ct                      IN CNAME         vlinks.mmailer.net.     <-- CONTACT  SUPPORT FOR THIS RECORD
_dmarc.mom              IN CNAME         _dmarc.mmailer.net.

You also need to add "include:_spf.mmailer.net"  to your existing SPF TXT record.  Contact our support team if you don't know what this is or who to do it and we will try to help.

Once you have completed this, please respond to or create a new support ticket so we can check.

Configuration Required for Sending through a Relay Partner

This depends upon which relay partner  you are using.  Please open a support ticket with our helpdesk team and let them know your sending domain, your account and contact information and the relay partner you  are using.   These are  some  of the records you need that will be the same no matter who you relay through, please program them:

mom                     IN TXT           "v=spf1  <CONTACT  SUPPORT FOR THIS RECORD>"
mom                     IN MX       10   <CONTACT  SUPPORT FOR THIS RECORD>
default._domainkey.mom  IN CNAME         _em._domainkey.mmailer.net.            
ct                      IN CNAME         <CONTACT  SUPPORT FOR THIS RECORD>
_dmarc.mom              IN CNAME         _dmarc.mmailer.net.

Conclusion

This type of configuration allows you to send under your own flagship and look more professional that many of our competitors which send their client's messages under their own domains.
