[Mailman-Users] not all messages delivered

[Michael Dosser]

hi all!

i've checked if somebody already asked this question and i have not seen
anything like this. if it has been asked once and i have not seen so i am
sorry.
we are using mailman 2.0beta2 in conjunction with sendmail 8.10.1
on freebsd 4.0 and it worked fine for over 1 month. our mailserver handles
several domains (~60) so we mapped as in howtos described between
virtusertable and aliases.
but now we seem to have a problem: mailman/sendmail does not deliver to
all the persons which are subscribed to two of our lists (one with
about 1200 and the other with nearly 1900 members). the system
maillog (/var/log/maillog) says that most of the messages were delivered,
but some 100 were not.
the mailman log (/home/mailman/logs/errorssays):
