There's no such thing as a local *real* folder created by MailMate, so 
that must be a "Smart Folder" whose contents are defined by some logical 
definition, drawing messages from some set of source folders that exist 
on the IMAP server.

MailMate does include by default a "Junk" Smart Folder that includes all 
messages from whatever server-side folders you've labeled (or MM has 
labeled by default) as having a "Mailbox Type" of "Junk" across all 
accounts. If there's not a top-level folder named "Junk" on the server 
side, I expect that MM would see one named "Spam" as the right folder to 
include in the "Junk" Smart Folder.

So my *revised* theory is that your Spam folder on the Fastmail server 
is set in MM as the Junk-type folder for that account, that they in fact 
did put the message in Spam, and you moved it elsewhere before noticing 
that it had been in Spam (which is down in the Sources section of the 
mailbox list where you might not see it.)
