[Zope] MailHost problem after upgrading to 2.2.4

[Edwin Martin]

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:

Can someone help me?
