They don't have to know the original poster's address in advance. Likely 
at some point in the past, they got a piece of spam with a spoofed from: 
address of [log in to unmask] and then added all of domain.com to their 
block list.

Based on these symptoms, I would say that it's some variation of the 
original poster's address being blocked, not the address of the Listserv 
machine. Since the OP's addresses vary, some posts are blocked and some 
are not. If it were the Listserv domain, you would see UNUSED in 
response to every post.

My advice to a subscriber having this kind of trouble is to either (a) 
turn off the block list and try again, or, more often, its (b) review 
the block list, taking note of the "count" of the number of times each 
item has been  blocked. More often than not, the person has some 
unwanted address or domain on that list, and didn't realize it. (Well, I 
guess they're *all* unwanted, but you get what I mean...)
