[exim] tiscali.be listening? Please fix your callbacks

OK - so one of our users on europe.com is facing trouble sending to
tiscali.be, with an error that looks extraordinarily like a failed
callback in exim

Sheesh. I just did another test now and chanced to be looking at my
mail logs, on the machine I was sending from

1. Their callback / sender verification is connecting to my box
frodo.hserus.net from which I initiated the test, and trying to verify
the sender. Trouble is, frodo is NOT an MX for europe.com, so these
people shouldnt be doing callbacks to the sending server anyway

2. Their callback script has a typo in it - it is issuing "quitr"
instead of the ESMTP QUIT verb
