[AusNOG] Is anyone on ausnog from gmail

[glenn.satchell at uniq.com.au]

Hi Tim,

Been through this recently. I have a couple of cloud VMs that need to 
send email from my domain. Adding openDKIM fixed that. There's a few 
resources on the net describing the procedure, searching for "install 
opendkim on ubuntu" or whichever linux distro you have will get you 
there. There's sites to test the headers, spaminess, etc, in the 
instructions.

DKIM adds an email header signed with a private key, the public key goes 
in a DNS record so the receiver can validate the header.

regards,

Glenn
