# Miscellaneous Preferences

# Debug

Toggle the output of debugging information. Depending on what notification priority set for it in the Display page, it can show up in list or dialog as the program runs.

# Empty Trash on Exit

Set Balsa to delete all messages in the `Trash` mailbox when Balsa exits.

# Close mailbox if unused more than

Set Balsa to close any mailbox that is unused for more than the specified time. The currently displayed mailbox is never automatically closed.

# Hide messages marked as deleted

When a message is moved to another mailbox, including the `Trash` mailbox, it is actually copied to the destination, and the original is marked as deleted. Deleted messages may either be shown in the mailbox index, with the trashcan icon indicating that they are deleted, or hidden. This item controls which of those actions is taken.

A message may also be simply marked as deleted, without copying it to another mailbox: Message Toggle flag Deleted . Again, this item controls whether such a message is hidden.

# Expunge deleted messages on close

“Expunging” is the act of physically removing from the backing mailstore all messages marked as deleted. You can expunge messages manually: Mailbox Expunge deleted messages , or you can set Balsa to expunge deleted messages when the mailbox is closed (all mailboxes are closed when you exit Balsa).
