A couple of days ago my mail server stopped working and all I'm getting is this
postfix error message:
muttley postfix/smtpd[2718]: NOQUEUE: reject: MAIL from localhost.localdomain[127.0.0.1]:
452 4.3.1 Insufficient system storage; proto=SMTP helo=<notify.ossec.net>
muttley postfix/smtpd[2718]: warning: not enough free space in mail queue: 17719296 bytes
< 1.5*message size limit
So I upped the limits of my postfix config settings to:
postconf -e "mailbox_size_limit = 1048576000"
postconf -e "message_size_limit = 30720000"
But still no joy.
Then I had a look at my free diskspace:

Apparently this is a known bug with ureadahead but I haven't been able to find anyone
else mention that it was affecting postfix:
https://bugs.launchpad.net/ubuntu/+source/ureadahead/+bug/501715
Anyway I installed the fix (https://launchpad.net/ubuntu/+source/ureadahead) but I'm
still getting the same errors. Is this the root of the problem do you think or is it
something else?
Can anyone help me out with this it's driving me nuts?!
Cheers,
Andrew
