Unless the sending mail server is completely broken, it will queue and
retry.

svc -d /service/qmail-send will allow qmail to accept mail via SMTP and
queue it, but not deliver it.
Making all possible delivery directories sticky will postpone all
deliveries.
IMHO, single-user mode, unmount filesystem, set up quotas, back to
multiuser mode is probably your best bet. Your odds of losing any mail
during this transaction are extremely low, unless the sending mail
servers are totally useless...
