[Zope] mail encoding problem

I'm trying to send a mail from Zope (2.6.2b3 on RH9.0) containing latin-1 characters using the following script invocations: # external method to quopri.encodestring encode=container.encode_quotedprintable container.MailHost.send(encode(body),mto=toAd,mfrom=fromAd,subject=encode(subject),encode='quoted-printable') This works fine for the Yahoo mail-client, but Outlook filters out special characters in subject and body. Does anyone know a solution to this problem?
