I have one user on my system who receives a LOT of spam. This is
intentional as that user is set to never discard email once it is
received. I scan the spam and let it auto-expire out of the IMAP
folder after 7 days. The trouble is, in those 7 days, the folder
usually grows to between 1500 and 3000 messages, and my sa-learn on
that folder simply grinds the machine down to a crawl. I've set the sa-
learn to process this folder in the middle of the night, but it is
still problematic and interferes with other late-night processes. It
has even, on occasion, necessitated a reboot when i could not get the
system to kill the process. I've taken to trying to scan it daily and
manually delete the spam, but that's not always possible.
The trouble appears to me to be that sa-learn has no concept of
whether or not it has learned a message or not. Since all IMAP
messages are stored with unique names, is there some easy way to
create a cache of the messages it has checked and have it ignore those
messages?
I suppose I could do something like:
find $HOME/Maildir/.SPAM/{cur,new} -type f -ctime -1 -exec /usr/local/
bin/sa-learn --spam {} \;
??
