I have upgraded my Zope to 2.2.4. Now my MailHost product will not work anymore. On the Zope website I can't find information to solve this. Before the upgrade, I had in the Zope-root a MailHost instance, which worked ok. After the upgrade, mail didn't work and when I clicked the MailHost instance, I got an error. I deleted the instance and now, when I'm addind a new MailHost instance, I get an error. I entered: Id: MailHost SMTP Host: <my-ip-number> SMTP Port: 25 When I look in Control Panel -> MailHost, I see a Help folder. This is the error I get after 'adding' a MailHost: <TD WIDTH="90%"> <H2>Zope Error</H2> <P>Zope has encountered an error while publishing this resource. </P> <P><STRONG>Resource not found</STRONG></P> Sorry, the requested Zope resource does not exist. --> <HR NOSHADE> <P>Troubleshooting Suggestions</P> <UL> <LI>The URL may be incorrect.</LI> <LI>The parameters passed to this resource may be incorrect.</LI> <LI>A resource that this resource relies on may be encountering an error.</LI> </UL> <P>For more detailed information about the error, please refer to the HTML source for this page. </P> <P>If the error persists please contact the site maintainer.
