I have got Mail's junk mail auto delete working now and thought I'd pass along my findings in case anyone else might benefit from my travails.
It appears that, as some who responded here noted, the auto deletion does occur only if the program (or maybe the computer) is shut down. I haven't figured out exactly when it happens, but I do notice that if I leave the computer on, with Mail active, for several days nothing gets deleted. If the "Move deleted messages to separate folder" is selected in the Accounts/Special Mailboxes preference tab the junk mail does not get deleted, even if the computer is shut down and restarted. So deselect that option if you have previously selected it. The junk mail that gets automatically deleted is, for reasons I haven't figured out, more than exactly one day old (or one week or however you've set it). For example, although I have mine set to delete junk mail that is more than one day old, this morning (March 18), after turning off my computer at about 5 p.m. on March 17 and turning it back on at about 8:30 a.m. on the 18th, I still have mail in my junk mailbox dating back to 5:30 a.m. on March 15. But at least it's working more or less like it should. | The next meeting of the Louisville Computer Society will | be March 22.
