[Mailman-Users] monthly reminder seems to overload our machine

[PalmConsult Markus Reichart]

Hello to all,

We running Mailman 1.0 using sendmail on SuSe 6.0 with 1200 users in one
mailinglist.
On every 1th of a month I see the same trouble:

mailman/logs/smtp-failures says:
Oct 01 05:00:19 1999 TrySMTPDelivery: To xxx at fh-wolfenbuettel.de:
Oct 01 05:00:19 1999 TrySMTPDelivery:

......eight error messages like above...
Oct 01 05:00:19 1999 TrySMTPDelivery: To xxx at mgi.de:
Oct 01 05:00:19 1999 TrySMTPDelivery:    socket.error  / (111, 'Connection
refused')  (deferred) 
.... hundreds of error messages like above...

Mail to the listadmin:
