<div class=Section1>
<p class=MsoNormal><span lang=EN-US>Hello all<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I have a problem, and discussing it on the
irc channel didn’t turn up any obvious solution.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Say you have more than 1 MS box scanning
mails for a specific domain. They are load balanced in some way, so the load is
split over the servers.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Now lets say one of the servers have a
problem. Not a fatal problem, so the server is still running (responds to pings
etc) port 25 is still open, and exim (the mta in my case) still accepts mails.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>But for some reason, crash, corrupt config,
full root fs etc. the process of moving mails from the incoming queue to the
outgoing queue is not working.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>What I am interested in, is a system to
alert me of such a problem automatically.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Currently the only thing, besides clients
noticing mail being delayed, is for me to look at my mailscaner-mrtg graphs for
the incoming queue and notice that its growing.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>One method of doing all this automatically
that we came up with, would be some complex system that would work as follows:<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>You create a domain for each MailScanner, that
only that MailScanner scans for.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>You then create an imap account on another
system for each of the domains.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>You then create a script that sends a mail
to each of the accounts and after X amount of minutes check to see if the mail
has arrived on the imap account. If yes, delete the mail and do the same thing
again after Y amount of minutes (a cron job), if it doesn’t exist
something must be wrong with the mailflow, either its interrupted or is
experiencing delays.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Do anybody have a better idea or know of
something that can do this already?<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>My root file system ran full last week, and
it caused mails to still be accepted (incoming is on /var on another disk) but
MS was frozen because it couldn’t extract attachments to /tmp which was
full because it was on the same disk as the root fs.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I hope I have made the above somewhat
clear, if not please ask me to clarify.<o:p></o:p></span></p>
