SA does know about mail it already learned. However, for various reasons
it is *not* based on the file name. An obvious reason would be support
for mbox format. :) And auto-learning before the mail has been passed
on to the MDA. Then there's the problem that even with Maildir format,
file names (think flags) are not guaranteed to remain static...
To determine if a mail already has been learned, SA needs to have a look
at the mail.

Something like that, yes. It definitely makes sense to 'find' the
messages delivered since the last sa-learn run. That line however is
*way* too inefficient, spawning an sa-learn Perl process for each
message.
Instead, call sa-learn a single time only. Probably by snipering the
last day's spam into a temp folder first, and simply pointing sa-learn
at that dir.
