I don't think this is needed. Postfix has configurable limits. In this 
case, there is a limit on the user's mailbox size. The loop will keep 
happening until the user's mailbox reaches the maximum. It should not crash 
or affect the server.  I assume Sendmail has similar configurable limits.

Only if the machine does not have sufficient disk space to support the 
mailbox size limits will there be a problem. In this case adjusting the 
limits is the solution.
