iTunes auto delete won't work -- fixed

I upgraded to a new computer with Windows 7 and moved my iTunes library to it. Right away I noticed that podcast auto delete was not working, even when I right-clicked on specific podcasts and made sure that "Allow Auto Delete" was on.

The fix was to open the podcast settings dialog and change the "episodes to keep" option. The problem is that in the latest iTunes, it's not obvious where to find that dialog box. It's not in the main preferences dialog. Instead find it by going to the podcasts view. Then look at the bottom of the window. You'll find "Unsubscribe" and "Settings..." buttons. Click "Settings...", then change the "Settings for:" field to "Podcast Defaults". Set "Episodes to keep:" to "All unplayed episodes".

Fedora, Postfix, and SELinux

Getting these types of errors in /var/log/maillog?

Jun 16 09:47:14 myhostname postfix/local[25474]: C269521F8C: to=, relay=local, delay=0.07, delays=0.02/0/0/0.04, dsn=5.2.0, status=bounced (cannot update mailbox /var/mail/root for user root. unable to create lock file /var/mail/root.lock: Permission denied)

You're running into SELinux denials for local mail delivery. In Fedora, correct that with:

# togglesebool allow_postfix_local_write_mail_spool

EDIT: I just realized that togglesebool only changes the running config and does not survive reboots. The permanent fix is:

# setsebool -P allow_postfix_local_write_mail_spool 1
