There's no real queueing mechanism with the smtp-forward plugin, the
mail will be rejected with a temporary error, which means the mail will
stay in the client's queue and sent later again... well at least for
most MTAs. Some are buggy that they don't get the difference between a
hard failure and a temporary problem and will not retry.
The otherqueue plugins (except for maildir of course) send the mails to the
local MTA's queue which then forwards to the remote system.
