When you receive following 'Undelivered Mail Returned to Sender' failure in your inbox when sending an e-mail it can have several causes, including your mail from being marked as SPAM by the receiving mail server. Please sent the entire message to us so we can take a close look at it and inform you what to do.
In general, to prevent your outgoing email sent from out of SpinOffice to be marked as SPAM, we advise you to have our mail server added to the SPF records of your domain. Your domain hosting provider will be able to to this in the portal area of your domain.
Add our mail server to the DNS-zone of your domain in order to have email traffic from our servers to be accepted by your mail provider.
The record that should be added is:
include:spf.spinoffice-crm.com
The SPF records will look as follow:
v=spf1 include:spf.spinoffice-crm.com -all
When this is done, your sent email will no longer be marked as SPAM.
