Had noticed for the last hour or so I hadn’t received any mails, very unusual.
Then I got a couple of messages on facebook, but no email notification. Very bad.
So ssh’ed on to one of my exim frontends, and the logs look pretty bad:
2008-06-03 21:39:59 1K3cFY-0004zM-Nt == <snip> R=internal T=remote_smtp defer (-45): SMTP error from remote mail server after MAIL FROM: <snip> SIZE=10797: host backend [x.x.x.x]: 452 4.3.1 Insufficient system resources
Hmm this is bad. Basically I have three exim frontends, all feeding to my Exchange 2008 back end. Unfortauntely as this is my personal mail server, my pennies don’t spread to contingency on the backend, i.e. clustering.
So all the mail at the moment is safely queue’d on the frontends, until I fix the Exchange server.
Think it may have 1) run out of space 2) as it is M$ and been up a while, need a reboot.
Sending this via mobile (well via email hosted elsewhere) will be fun to see if it get’s into the exchange, and then to the blog. This actually wont post until I fix it all
