In the current default configuration, the mailserver can run out of
vpm-pfpolicy resources under high mail load.  vpm-pftransport runs after
the message is accepted and runs the anti-spam settings, so needs to be
limited to keep the load on the system down, however, vpm-pfpolicy consumes
very little system resources, and you can run many instances.

In /etc/postfix/master.cf, the section

#  vPostMaster setup
vpm-pfpolicy  unix  -       n       n       -       5       spawn
  user=vpostmaster argv=/usr/lib/vpostmaster/postfix/vpm-pfpolicy
vpm-pftransport unix  -       n       n       -       5       pipe
    flags=Fqhu user=vpostmaster argv=/usr/lib/vpostmaster/postfix/vpm-pftransport $sender $recipient

You can change the vpm-pfpolicy line to

vpm-pfpolicy  unix  -       n       n       -       -       spawn

to allow up to the default (100) number of processes.  When you're
finished, restart the postfix server.

/etc/init.d/postfix restart
