Majordomo is through reading the list as soon as it returns. Your MTA,
however, is probably not finished reading the list then, and may not have
even started (because the message to the outgoing list can be queued and
can sit around for a indefinite amount of time). You'll have to figure out
when your MTA is done before you can delete the file.
If you're using TLB or bulk_mailer, you can delete the list as soon as it
exits because the MTA gets the addresses from (TLB|bulk_mailer) and not
from the file.
