[comp.mail.headers] Strange `From ' lines

jeh@crash.cts.com (Jamie Hanrahan) (12/28/87)

Following are headers from two recently-received mail messages.  
Why are those "From" lines coming out like that?  Based on the other 
headers and the contents of the message, I gather the second one should 
be something like 

	From crash!nosc!NIELAND%FALCON@WPAFB-AAMRL.ARPA

instead of

	From crash!FALCON!nosc!!WPAFB-AAMRL.ARPA:NIELAND

A similar, but not identical (or maybe it is; I'm getting confused) 
transformation seems to have occurred on the first message.  

My local sysadmin says his mailer isn't doing it...
