Not to forget that the very 'technique' which once gave QMail an advantage -
that of opening a separate connection for each message/recipient on a target
destination - has become associated with certain spam techniques.
Hitting an 'smtp_accept_max_per_host' limit and having to retry later may very
well negate that 'advantage'.
