For the spamtraps, I have an address hidden from human view on our
web pages but obvious to bots. I also looked at the 550 rejects we
were sending and picked several names that it seemed everyone was
trying to send to. These were then all entered as aliases for my
spam folder using Workgroup Manager from the OS X desktop.
Also, when some site insists on an e-mail address, I give them one
that goes straight to the spam folder.
sa-learn is called from cron once an hour, I modified the script to
learn and then deleted the messages in both my spam and ham folders.
