I have a domain mysite.mydomain.com and it has two MX records. I have Indimail installed and working fine.
I have added a spf record like below
v=spf1 mx a ip4:x.x.x.x/32 ip4:x.x.x.x/32 ~all
I have configured, DKIM in Indimail and placed DNS record accordingly as well. I have configured DMARC as well.
My application send an email out of using Indimail server which is my in MX records.
For a specific requirement, From ID would be firstname.lastname@example.org.
This application is used by customer as well and when customer submits a feedback option, application hits my website mysite.mydomain.com.
But they get a warning message that “mysite.mydomain.com” is a suspicious domain.
As the From-ID domain is different than my original domain mysite.mydomain.com, I thought SPF and DKIM record should consider the email as genuine emails. Though the emails are not marked as spam, but still SPF alignment is not crossing 28% and DKIM alignment is 0% from customer DMARC report for my MX servers.
DMARC report for my domain shows as 100% alignment for DKIM/SPF.
Need your help here. Basically, I need to “Send email from another domain without being spam”.
I have created an account in postmarkapp and configured DMARC record for getting a report.
I received weekly report and report shows that our mails were 100% SPF aligned and 99.8% DKIM aligned.
Whenever the email is triggered with from-id as @my-domain to @customer-domain via my Email Server SPK/DKIM/DMARC is getting passed.
And when email is sent with from-id as @customer-domain via my email server, SPF/DMARC is getting passed and DKIM is failed as the DKIM-signature is configured only for my-domain. "
Customer has updated their SPF record, with my-domain in the include flag.
