I just saw this article at Wired and realised one of the benefits of working for a smaller organisation - this is not me I'm talking about, but you. One of the worrying quotes was:

The survey gathered responses concerning e-mail security from 406 companies in the United States and the United Kingdom with more than 1,000 employees.

In both regions, 38 percent of respondents said they employed staff to read or otherwise analyze outbound e-mail. In the United States, 44 percent of companies with more than 20,000 employees said they hire workers to snoop on workers' e-mail.

Wow, not just the US, but the UK too.

Now, should your customer be in the business where they do need to analyze mail, then of course SBS can help - for details on how to set it up, go have a look at the forum entry - http://uksbsguy.com/forums/thread/334.aspx for the answer  - simple and effective.
