Ensuring reliable email delivery from Blueprint OMS


Email sent through Blueprint OMS is sent by Blueprint Solutions on behalf of the sending domain (e.g. myhearingclinic.com).

In many cases, the receiving mail server will classify these messages as spam (fraudulent or unsolicited email), if they are unable to verify that Blueprint Solutions is authorized to send email on your behalf.

Fortunately, there are steps you can take to ensure reliable message delivery, and these are outlined below.

Some of the steps are technical in nature, and will need to be handled by the person or company that manages the clinic's website, domain, or email accounts.

How to ensure reliable email delivery

SPF and DKIM records on the sending domain tell the receiving server that Blueprint Solutions is authorized to send email from that domain.

Send from a domain that you own

The required SPF and DKIM records can only be added to a domain that is owned by the clinic. They cannot be set up for free email addresses (e.g. Yahoo, GMail, Hotmail, etc).

Add SPF and DKIM records to your domain

Add an SPF record to your domain's DNS settings

Create a TXT record with the following value:

v=spf1 include:spf.mandrillapp.com ?all

If your domain already has a TXT record with SPF information, you'll need to add our outbound email servers to that record by adding include:spf.mandrillapp.com in the record (just before the last operator, which is usually ?all, ~all, or -all).

Add a DKIM record to your domain's DNS settings

create a TXT record for mandrill._domainkey.<your_domain.com> with the following value:

v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCrLHiExVd55zd/IQ/J/mRwSRMAocV/hMB3jXwaHH36d9NaVynQFYV8NaWi69c1veUtRzGt7yAioXqLj7Z4TeEUoOLgrKsn8YnckGs9i3B3tVFB+Ch/4mPhXWiNfNdynHWBcPcbJ8kjEQ2U8y78dHZj1YeRXXVvWob2OaKynO8/lQIDAQAB;

Note: Please ensure that there are no spaces in the p=MIG... portion of the DKIM record.

Verify your domain

Our mail delivery provider (Mandrill) also requires verification that Blueprint Solutions is authorized to send email from the domain.

To verify your domain, please send an email to verification@bp-solutions.net from an email address in your domain (e.g. jane@myclinic.com), with the subject Domain verification.

You will then receive a message like the one below:

Subject: Verify your domain for Mandrill

Mandrill domain verification
The Mandrill account with username aleem@bp-solutions.net is attempting to
use an email address at your domain (blueprintsolutions.us).  To allow this
account to send from your domain, click the following link:


To complete your domain verification, simply forward that message to verification@bp-solutions.net (ignoring the instructions to "click the following link" which appear in the message).

What happens if I haven't followed the steps above?

Mail sent through Blueprint OMS will continue to be delivered (including from addresses from GMail, Yahoo, etc).

However, the messages will be delivered with the following minor modifications:

Most email software will correctly reply to the Reply-To address rather than the sending address (blueprintoms@bp-solutions.net), however this is not always the case.
