One more thing. Why on earth "-vvv"? That triggers extremely verbose
Postfix logging, likely logging every line of eavh queue file, perhaps
more than once. Your syslog bandwidth might then severely limit
performance. DO NOT do that! If Postfix is slow, the last thing you
want to do is crank up logging to insane levels.
