This is the master on/off switch for feedmail message queuing.
Queuing is quite handy for laptop-based users. It's also handy if you
get a lot of mail and process it more or less sequentially. For
example, you might change your mind about contents of a reply based on
a message you see a bit later.

There is a separate queue for draft messages, intended to prevent
you from accidentally sending incomplete messages. The queues are
disk-based and intended for later transmission. The messages are
queued in their raw state as they appear in the mail-mode buffer and
can be arbitrarily edited later, before sending, by visiting the
appropriate file in the queue directory (and setting the buffer to
mail-mode or whatever). If you visit a file in the queue directory
and try to queue it again, it will just get saved in its existing file
name. You can move a message from the draft to the main queue or vice
versa by pretending to send it and then selecting whichever queue
directory you want at the prompt. The right thing will happen.

To transmit all the messages in the queue, invoke the command
`feedmail-run-the-queue' or `feedmail-run-the-queue-no-prompts'.

You can customize this variable.
