Sender Domain Management

Starting from Octeth's v5.1.0 release, Sender Domain Management offers a great deal of power and control. This feature allows the system owner to set up unique email delivery environments for each user account. It also enables the allocation of dedicated email delivery IP addresses, sender domains, and tracking domains. Should a user experience high spam complaint or hard bounce rates, the problem will remain isolated to the dedicated IP address and domain, and will not impact the other users.

ℹ️
Sender Domain Management is a feature that can be found in Octeth versions v5.1 and higher.

Setting Up DNS Structure For Email Deliverability

In order for users to send email campaigns and auto responders, their sender domains must be verified and authorized. This necessitates configuring the DNS structure in order to guarantee proper email deliverability.

You can configure the DNS structure in the /opt/oempro/data/config.inc.php file by editing it and locating the function that is displayed below:

Let’s say, your primary sender setup domain is abc.com. You will just ago ahead and setup SPF, DKIM, DMARC, MX and other records on this primary domain. Your users will just inherit the setup from this sender setup domain.

Here’s an example primary sender setup domain DNS record list:

HOST
DNS TYPE
VALUE
abc.com
A
<octeth_server_ip_address>
bounces.abc.com
A
<octeth_server_ip_address>
track.abc.com
A
<octeth_server_ip_address>
abc.com
MX
bounces.abc.com
abc.com
TXT
"v=spf1 ip4:…. include:…. -all”
_dmarc.abc.com
TXT
“v=DMARC1; p=none; ….”
key1._domainkey.abc.com
TXT
“k=rsa; p=….”

Based on the example above, the DNS structure can be configured like;
