LISTSERV, as well as your email software (whether it's LSMTP, sendmail, or another)
should continue to resend the email as long as the time limit set for, say, 1 day.  If it
continues to fail after a certain amount of time (the default is usually 5 days) it will then
be deleted from the system.

I hope this helps.
