It won't.  /dev/stdout means something different to each process; it
refers to the process's own stdout, which in this case is the pipe
that messagewallstats is reading from.  tee will write its input to
the pipe twice (with unknown interlacing due to possible buffering),
if it even works at all.  messagewallstats' output will be emailed.
Nothing will be written to the rotated log file.

So you want the rotated log to contain exactly what was in the
"current" file, without any processing applied to it, and you also
want the output of messagewallstats to be emailed?  Then this will
work:
"!messagewallstats | qmail-inject postmaster && exec cat previous"
