A _sane_ delivery agent would definately return a temporary error (4xx)
either to it's own internal queue, or return the error to the connecting MTA.
The mail would in that case survive for a queueing period which is
usually 5 to 7 days.
But, when it comes to procmail, it might depend on your invocation:
On general failure procmail will return EX_CANTCREAT, unless
option -t is specified, in which case it will return EX_TEMPFAIL.
Are you using sendmail or some other mda?
Investigating sendmail source you'll find:
* EX_CANTCREAT -- A (user specified) output file cannot be
* EX_TEMPFAIL -- temporary failure, indicating something that
* is not really an error. In sendmail, this means
* that a mailer (e.g.) could not create a connection,
* and the request should be reattempted later.
status = "5.3.0";
Unfortunately, for you, if -t was left out, it would mean a 5xx error code
- permanent error - and a /dev/null of your email.
