Cannot receive email from certain domain

[DLS75]

I cannot receive email messages from @smithmur.com.  It is very important that I receive messages from this company. It is for my job.  I checked spam folder (empty), trash, and all other folders; messages not there.  If this domain is being blocked, please unblock as soon as possible.  I would appreciate a response here.

EMail from my customer is ending up in my Spam folder. Email from this customer is not Spam to me. All emails from domain "huvaere.com" are deposited in my Spam folder. Can you fix this? If so, then please fix this. Thank you.
