Anyway, back on topic, the easiest way to interpret exim log files is to use eximstats utility that comes with it. You can do that directly on your server by running it from shell, or you can download exim source code, locate eximstats script and run it on your local computer where you downloaded that big log file and look at the output (eximstats is a perl script, so you'll need to have perl on your local computer). You should also be able to access eximstats generated statistics from cPanel, by going to WHM -> Email -> View Mail Statistics. And when you determinate whether those e-mails originated from your server or not, you can take appropriate measures. In case that they were not sent from your server, your client was probably a victim of a backscaterrer spam run (spam e-mails sent with his e-mail address as sender, so that broken spam scanners send rejections back to that address and overflow its mailbox). Bounce messages from such spam run, can be handled to a certain extent by using Spamassassin with its VBounce plugin enabled, and also by denying access to the MTA using a few of the backscaterrer block lists (just make sure not to apply such rbl to postmaster/abuse e-mail addresses, which should accept all e-mail). On a side note, I prefer Postfix much more over exim, but I don't know if cPanel can use it (If I remember correctly, cPanel is setup for exim only). Also, I would suggest you to switch to Dovecot for IMAP/POP3 from Courier (Dovecot is supported by cPanel).
