zemon@felix.UUCP (Art Zemon) wrote that sendmail delivers about 30
addresses out of 100, queues the rest for later, etc.

It is possible that the sendmail.cf has the x option enabled.  A 'Oxn'
line in the config file or a '-oxn' flag in the argument list to
sendmail will tell it to stop processing messages when the load
average gets above 'n'.  Also be aware of the c, q, s, X, y, Y, z and
Z options, which can affect sendmail performance on large mailing
lists.

A temporary solution is to comment out all of these options, refreeze
the .cf file and restart sendmail.  Then try it again.

The problem is that large mailing lists push up the load average, and
sendmail will defer processing until the load average gets back down
to a reasonable level.
