My inbox has been polluted by a rash of these this week.  They're so badly formatted, it's hard to believe anyone would fall for them.  The spammers haven't even tried to make the reply-to address look legit.  Some have a sender name from UPS but use the FedEx logo.  Like this site, I'm assuming these are malware delivery devices, but don't intend to experiment. 

The senders have included:

U.P.S.Service [no.reply@fortwayne.com]

logistics UPS [no_reply@arlington.com]

UPS Mail [NOreply-RC@tulsa.com]

UPS Office [NoReply.RX@denver.com]

First-Class logistics [no_reply.JAU@shreveport.com]

First-Class logistics [support.264@lasvegas.com]

First-Class Mail Postal Service [769.JT@sanfrancisco.com]

The subjects have looked like:

Number (A)BQQ16 414 272 1170 9681

Tracking Detail (P)LAQ53 129 880 0685 1561

ID (O)JB19 720 719 5134 5558

Here are three examples of the format:
