External Method to change SMTP servers on all sites in a Zope

In ZMI add an External Method (specify "change_smtp_servers" for all the values) after placing this file into your $INSTANCE/parts/instance/Extensions or $INSTANCE/parts/clientX/Extensions directory. This doesn't work as a Script (Python) because of restricted Python. Check the current source at https://svn.it.uwosh.edu/svn/plone/Scripts/change_smtp_servers.py
