I'd guess that depends on the system setup. If majordomo creates an
outgoing mail for every recipiant, sendmail will have to handle each one
individually. If your sendmail is single threaded (I guess it is), it
will take at least 8 hours to send 30000 mails, if every mail consumes
only one second. If your mail uplink (the server getting all your mail
from _your_ sendmail) isn't fast it may take considerably longer...

Can you split the list and use a second majordomo on a second server to
double (at least) the throughput? Could you use a sendmail program that
handles more than one mail at a time?
