Greig's cool find of the day:
Exim comes with a script called exipick, which lets you see just the parts of the mail queue that match a particular pattern. ie. we want to get notified of messages that are queued on a backup MX, but aren't just bounces to fake addresses that will eventually time out:
exipick '!$local_error_message'
Which makes looking at mail queues much easier:
root@elston:~# exipick | wc -l 96 root@elston:~# exipick '!$local_error_message' | wc -l 0
My find is a little less interesting, and a little more "just googled it", but if you have certificates in Apache crt/key format, and you want to import them into IIS, you can
do so with openssl:
/etc/ssl/site.net.nz# openssl pkcs12 -export -out site.p12 -inkey site.key -in site.crt
