Howdy all.

 I have a user who states they are not receiving emails from a specific company.  She can send to them just fine, but when they send a new or even reply to her emails, she doesn't get them.  We are having no issues receiving outside mail otherwise.  Their IT person sent me a copy of their logs that clearly states the email is being delivered to our server, so where is the email going?  It's not being caught by our SPAM filter or her junk folder.    I have SMTP logging turned on for the receive connector but don't see anything in there from this company.  

Here is a copy of their send logs.
