Google and all the major e-mail providers recently started enforcing the requirement for DMARC, DKIM and SPF for the sending of e-mail.
Our Bulk Email Servers (BEMS) "spoofs" the from address for shop offer e-mail using the e-mail address of the logged in scheduler who is posting the session. It is critically important that your schedulers only use e-mail addresses that you have properly configured to be spoofed. They should NEVER use a Gmail address.
For an example, they would all have @your_system_domain.com email addresses.
In order for our servers to have permission to do this, you need to make sure your DNS records have been updated to the e-mail provider standards.
Please let us know after you have done this so we can finish the configuration on our end and so that our system admins can test the e-mails from the system.
Changing DNS records is very dangerous, as you can disrupt your own e-mail receipt and/or break your corporate website if you do it incorrectly.
Please have someone who is well-versed in DNS settings make the following updates, as needed:
SPF
You need to add "include:_spf.sassieshop.com ~all" to your existing TXT SPF record in your DNS settings for your_system_comain.com
DMARC
If your DMARC record is invalid, you do need it set to "quarantine" or "reject". Make sure there is nothing wrong with the format of the record.
DKIM (digital signature)
You need to create this DNS record:
sassieshop._domainkey.your_system_domain.com IN CNAME dkim.sassieshop.com
