3565584 - E-mail Campaigns are not reaching user's Inbox

When sending e-mail Campaigns, even though in C4C it was finished successfully, the e-mails are coming to Spam or Junk folder instead of the Inbox.

1. Go to Sales Campaigns > Campaigns.
2. Open the desired one.
3. See it says Finished Successfully.
4. However no e-mails were received in the Inbox.

If the emails are arriving into Spam/Junk folder, it is because of the user's e-mail application settings. It is blocking the domain. 

This should be changed in the Email App used. For example, in Outlook it can be solved by right clicking on received mail and click on 'Never block sender's Domain (@example.com)'. Similarly for other domains.
