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 [email protected]" 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. -kevin
