This won't tell you whether IMAP or POP was used, but you can look at the 
atime on the inbox to see when it was last read.

The problem I ran into with this approach was that my verify pass on my 
backup job would read every file on the system, touching the atime's. To 
get around this, my verify script would remount the filesystem with noatime 
for the duration of the verify. So there was a window of an hour or two 
during which I might miss a user's access.
