[Zope] problems with MailHost

[Robert Rottermann]

Hi there,

I started to use MailHost on a Zope 2.42 installation.

What I do is as follows:
<dtml-sendmail mailhost="MailHost">
  to: robert@redcor.ch
  subject:Das ist die Testmail
  from:Halleluja

  Das ist der Body von dieser Mail
</dtml-sendmail>

I get a traceback as included.
Now my questions:
What could be the reason?
There were updates to the MailHost. Can I use the ones from the CVS trunk?
If not is there a Zope 2.42 (or 2.43) compatible version?

Thanks
Robert
