switches. Works great, but you have to invest the time to set it up.
Probably not much work for just a couple hosts. Lots of work for dozens of
servers, switches, routers etc. But worth it...</FONT></SPAN></DIV>

MailScanner discussion<BR><B>Subject:</B> OT: how to check everything is
working<BR></FONT><BR></DIV>
<DIV></DIV>Hi, i've just had an strange scenario, on one of my servers cent os
the I/O controller just stoped working, and all FS went to Read Only. I actually
check this:<BR><BR>sendmail online<BR>mailscanner online<BR>load<BR>disk
usage<BR>clamav pattern<BR>ram/swap used<BR>incomming messages
waiting<BR><BR>this is reported to a mysql and showed in a webpage. <BR><BR>the
problem is that this was working, but the server started rejecting all emails
with a 421 error "Can't write to the disk" so all trafic went to the second MTA.
so nobody realised that the server was down...<BR><BR>I started a google search
and i found this "mailping" <A
href="http://mailping.sourceforge.net/">http://mailping.sourceforge.net/</A> but
it seems to be a dead project.<BR><BR>so is anyone using something like this? or
has any idea?<BR><BR>Regards <BR><BR>Eduardo<BR></BODY></HTML>
