Is it possible that the site has been black listed?

When I register as a new user the site tells me that further instructions have been emailed to the address I've provided. However, I do not see the mail being generated in /var/log/maillog.

I can manually send email from the box, bot from the command line and via php, so I'm a little lost. I'm tempted to just start upgrading.

Anything in the watchdog log that might give a clue? You probably have some contrib module getting in the way of the mail being sent. Try disabling modules 1 by 1 to determine if that is the case.
