This won't really solve your problem, but just for fun, here's what a major 
perl guru had to say last time someone on the mod_perl list started 
discussing regex's to detect allowable characters in email addresses.

This is neither necessary nor sufficient.  Please stop with this nonsense.

**************************************************
*  An email address can have ANY CHARACTER OF THE PRINTABLE ASCII SEQUENCE.
*
*  An email address NEVER NEEDS TO GET NEAR A SHELL, so ALL CHARACTERS
*  ARE SAFE.
**************************************************

scream.  Matter of fact, I already did. :)
