How to produce a temporary error for the MTA?

Hello,

I have an account, where I have  to  do  sometimes  mainenance  and  any
deliveries could cause errors.

What I like to do is to touch a file which then is detected by  procmail
and produce a temporary error.

How can I do this?

The base  construct  at  the  beginning  of  the  procmailrc  should  be
something like:

----8<------------------------------------------------------------------
:0
* ? test -f ~/.procmail_tmp_nodeliver
{
    instruction which produce an temporary error
    for the Courier-MTA
}
----8<------------------------------------------------------------------


Thanks, Greetings and nice Day/Evening
