fail2ban is designed to ban ip addresses when someone tries to authenticate against *your* box nd fails the specified number of times. It is generally used for things like banning ip's that are dictionary attacking you ssh server or something along those lines. I'm not sure its really suited to do what you want.

Does the authentication failure get to /var/log/exim4/paniclog? that thing is empty unless there is a real problem, so just checking the file size of panic log would be simple and straightforward.
