By default (without any configuration), Unimarket sets the MAIL FROM in the email header to bounce@<your unimarket domain>, e.g. email@example.com. This stops emails from bouncing. We then set the FROM to your community defined customer email domain so that the recipient's email client displays the FROM address (your email domain) but 'via Unimarket.com'. Please note that this can display in email clients differently. Some show ‘via Unimarket’ ,while others may just show your email domain.
Example of what the recipient sees in the From inside Gmail:
Return Path Setup
If you want to ensure that all emails display as coming from your email domain and not 'via Unimarket', then a Return Path can be configured. This tells the recipient's email client that Unimarket is authorised to send emails on your behalf and it doesn't get marked as spam.
With a custom Return-Path, you can set your own return path email address e.g. firstname.lastname@example.org in place of ours.
The Return-Path is used to set the SMTP header MAIL FROM
When using the Return Path option you must setup a CNAME entry to your DNS that maps the domain you provide to our domain. So if your return path is email@example.com and the CNAME should be bounce.customerdomain.com---> unimarket.com. Use the Validate Return Path button to test if the CNAME you have setup in your DNS matches the Return Path.
Once setup, your Community administrator can enter the return path (e.g. firstname.lastname@example.org) under Email Delivery Authentication on the Administration / Settings / Profile screen. Please note that the return path needs to have the same suffix as the From addresses, i.e. if the From address is customerdomain.com, then the return path needs to be <something>.customerdomain.com.
