Problem
Customers are not receiving your emails.
With all of the deliveries that you may be doing for your customers, there are also a lot of email alerts being sent to your customers. One email thanking them for placing an order with you, another letting them know that their package was picked up and one for the final delivery. If your customer has a lot of orders with you, this can mean that their inbox is getting full of email notifications coming from your X Dispatch Server. With so many email messages being received by your customer from your X Dispatch Server, your customer's email hosting provider or email server may be falsely marking the email alerts you are sending as spam. If this occurs, your customer may eventually stop receiving your email alerts all together.
Solution
If you believe that your customer's email server may be blocking your email messages, you can configure the Mail Manger to relay your email messages using your company's email host SMTP Server. By doing so, the IP address sending the email will match the IP address of your company's email hostname, which will then pass a Reverse DNS lookup.
In X Dispatch, go to Action -> Mail Manager to open the Mail Manager.
Go to Tools - > Edit Profile to display the Mail Accounts.
Select your Mail Settings account and click Properties.
Enter your company's email host SMTP Server in the SMTP Server field. If the SMTP Server requires authentication, enter the SMTP Login and SMTP Password.
