If the problem is excessive load because Sendmail / Mimedefang / spamd / etc. is too busy handling tons of mail/spam being dumped on your server, you might want to look at these sendmail options: ConnectionRateThrottle (34.8.12) MaxDaemonChildren (34.8.35) also QueueLA (34.8.50) RefuseLA (34.8.54) setting these can keep Sendmail (and Mimedefang, spamd, etc.) from overwhelming the system. > > > > > Rainer > > Max > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos > > -- Robert Heller -- 978-544-6933 / heller at deepsoft.com Deepwoods Software -- http://www.deepsoft.com/ () ascii ribbon campaign -- against html e-mail /\ www.asciiribbon.org -- against proprietary attachments
