Seems to me the problem of jnos filling up a directory was a problem of a race condition caused misconfigured mbox, so that when smtp tried to deliver an undeliverable message it tried leaving it in mqueue, but it left only a blank message and incremented sequence.seq, then tried again with the same result. Stuck in a loop which ended up filling up the mqueue directory and finally the system would crash.
I too can't remember how exactly I got rid of the problem, but I do remember flushing mqueue and deleting sequence.seq (it regenerates on the next boot). And of course solving the ampr.org addressing problem. Look at the alias file and the ftpusers files. Check logs too... jnos and syslog for clues.
As for the thumb drive... I have the same as KD6OAT: a thumb drive with jnos on it, and the OS on the SD card. It's been running without problems since PI's became available here in Vancouver, so thats several years now.

Neither SDs nor thumb drives have the automatic redistribution logic of SSDs, so using them to write data that is being repeatedly altered (like log files and email folders) can really impact them. Thumb drives do seem to survive better than SDs, but SSDs are much better still.
