Of course, butas it is legal to abort the run one should be prepared
that this could happen. Some large list processing sites are rumoured
not to retry mails that are undeliverable in the first try, so
everything not explicitly forbidden should be weighed when deciding
wether to violate the RFC a little bit or not, especially when dealing
with customers' mail.
