We are having a production Issue. We recently switched to Aspose and used Aspose.Network to send emails out from our application. We used to use different tool to send these emails out and we never had any problems.
Now when these emails go out using Aspose.Network, it goes right into receipient’s “Junk Mail” folders. I checked the emails and they are identical, I checked the SMTP headers of emails and there are some differences. I am pasting the SMTP headers below from both emails, one that is being send out by Aspose and goes to their junk mail and second is the one that was send out by other tool and goes to their Inbox folder.
Please suggest what needs to be changed and why is the Microsoft IMS does not recognizes these email as safe emails?
PS I need to resolve it ASAP since its happening to our live customers!
Here is the SMTP Header of email that is being send out by Aspose and Goes to JUNK folder:
