The watchdog timeout is a safety feature to prevent Postfix from
becoming "stuck" due to a bug in system or Postfix software. It
also triggers when processing one message takes an unreasonable
amount of time.

With daemons such as pickup, the watchdog timeout is 1000 seconds,
and it is not configurable for a reason. Body checks also apply
to mail that arrives via SMTP, and you have no control over the
sender's SMTP timeouts. They won't wait 1000 seconds.

When it takes 1000 seconds minutes to send mail into Postfix, then
the timeouts are telling you that you have a problem. Timeouts are
your friend. Cure the disease, instead of suppressing symptoms.
