One of our clients seems to be sending an excessive amount of emails. In WebHost Manager, under Email->View Relayers the client has a "Messages Sent" of 985. Everyone else has less than 100. So if I click on them for more details, there are some emails from a normal user (client-user@client-domain.com) which seems to be normal. But then there are a ton of emails from
client-username@our-server-domain.com, which seems odd. I can't find a way to view those messages, so I can't see what they are. I have the message ID, but I can't click it to view the message like I can under Mail Queue. How can I view the email? And what should I do to look into this, to see what is causing it?
[EDIT] Perhaps a php mail form is being exploited. There is a DynaForm on the clients website...
