This problem is not specific to z3c.pagelet.

The publisher catches all errors and reports them to the error reporting 
utility. Note that the error reporting utility also forwards the exception to 
the logs. Next the publisher looks up a view for the error and displays it.

This gives you several ways to hook into the error handling.

- Have specific exception log handlers that send out E-mail. This is a matter 
of configuration in zope.conf.

- Write custom error views. You then have full control of what you want to do.
