If you need to enable all emails to be received from a particular sending email address - so that even sends classed as 'junk' will arrive - at that point you can 'whitelist' this location inside Junk Mail Filters inside the package.
1. Login to Hamro.Cloud
2. Select the package where your mailboxes boxes are found
3. Find the Junk Mail Filters symbol
4. Find Allow by Sender and include a space rule or a mailbox to enable mail to dependably be received from a particular location
