Hi, I've been using Linode for several years, and around may I started receiving less and less emails from my site (it's always been problematic - with people often never receiving access codes for classified ads posted on wordpress, site registration emails - it's now escalated to the point where when I submit a test email via my contact form it doesnt even appear in my mail.log)

root@server1:~# hostname -f
server1.cravenpublishing.com
I am able to receive mail fine using the command
root@server1:~# echo "test message blah blah" | mail -s "test message" mark@cravenpublishing.com
