Are apostrophes valid in an email address?

I've had a mailman subscription request from an email address that looks like this:
paddy.o'hagan at foobar.org (this is not the real address; the domain has been changed to protect the innocent from spam)
I've had a dig through google and haven't found any comprehensive definition of what is a valid list of characters. It occurs to me that a single quote could b0rk a number of poorly written CGI scripts and be rejected by the more secure ones. The spamex.com/xemaps.com DEA service rejects it as being an invalid email address.
The pending moerator request has come through to me, so mailman clearly thinks the address is valid.
