I added the sender ID some time ago, but when receiving email sent by MailBuild, it still shows as sent by createsend1.com
The headers also show
Received: from m4.campaignmonitor.com
Received: from [22.214.171.124] by createsend1.com via HTTP
A bit confusing as your guide says to add cmail1.com anyway,
so which should it be??
Apologies for the confusion, it can certainly get a bit complex at times. basically, the Sender ID record at cmail1.com covers all our sending servers for both MailBuild and Campaign Monitor. So, using include: cmail1.com will keep you covered for both apps.
Hi Dave, sorry for being a bit thick, but I 'think' my question is still unaswered?
I have the DNS txt record set as mydomain.com. and "v=spf1 mx include:cmail1.com ~all"
So why does OutLook show "Received from: Createsend1.com" :
... and are the headers showing the above??
Sorry, but really would like to understand this one.
It is tricky, but basically, this is how it works:
You send the email, using your authenticated domain.
When the receiving mail server lookups the createsend1.com address it is referred back eventually to cmail1.com as the source for all email through createsend1.com
Then it can verify that your 'from' domain has a record which authenticates cmail1.com as a sender of email for it.
Is that any clearer? Basically, it does work with just the cmail1.com in your DNS record for all our sending domains.
I think I need to clarify a little.
I added the SPF record to my domain so that veryfies fine.
But the example I gave was for an email sent by a client. Do they also have to add your domain to their DNS settings, or do they add my domain??
You need to add DSN records to whatever 'from' domains you are using in your campaigns.
