Look at what your MTA is sending as the From address (not the From:
address).  My assumption is that your RT server has an invalid
hostname and it's talking to mx.eon.ie and saying "Hi, I have mail
from www-data at invalid.hostname" and being told to go away.

Sending attachments shouldn't affect this.
Also, mail from your account isn't a good test unless it's also sent
by a web process running under apache with identical mail configs to
RT.
