GETTING STARTED

MX Records & Outbound Smart host

United States

In order for us to filter your emails, you will need to change your MX records to point at our service. You should use the same MX records for all domains you add to our system.

 

MX Record	Priority
usa.mx1.mailanyone.net	10
usa.mx2.mx25.net	20
usa.mx3.mailanyone.net	30
usa.mx4.mx25.net	40

We also encourage you to relay your outbound mail through our service to enable the full range of functionality. To do this, you will need to configure a smart host or outbound relay addresses on your mail server.

Example: Your smart host should read:

 

Smart host

usa.outbound1.mailanyone.net

Firewall IP ranges

 

To ensure spammers cannot bypass our system and deliver mail directly to your server, we recommend you lock down your network so that your mail server is only able to receive SMTP connections from our platform. To ensure that this is achieved, please configure your firewall or mail server to only accept connections on port 25 from only the IP ranges below:

Recommended - For maximum redundancy, allow access from all of our US ranges:

 

Subnet IP		Subnet Mask		Net Mask		IP Range
208.70.128.0		255.255.252.0		/21*		208.70.128.0 - 208.70.136.255
72.35.12.0		255.255.255.0		/24		72.35.12.0 - 72.35.12.255
72.35.23.0		255.255.255.0		/24		72.35.23.0 - 72.35.23.255

* CIDR Breakdown for customers using O365 mail server  which only accepts CIDR format ranges of /24 or smaller.

208.70.128.0/24	208.70.131.0/24	208.70.134.0/24
208.70.129.0/24	208.70.132.0/24	208.70.135.0/24
208.70.130.0/24	208.70.133.0/24

SPF Text Record

 

We encourage setting up an SPF text record in your domains DNS which designates our SMTP mail servers as authorized servers to send on behalf of your domain. Please note that if you do not already have an SPF text record you will need to add in IP's and domains that encompass ALL of the mail servers that you use to send mail from.

 

v=spf1 include:spf.mailanyone.net ~all
