[Zope] Bug in sendmail tag?

[Cornelis J. de Brabander]

Hi all,
I'm stuck with the following code. In zope 2.5.1 this code results in an
attribute error with error value 'sendall'. In zope 2.4.3 it works. I've
noticed there are differences in smtplib.py between the two versions. But
the code I use is correct according two the DTML Reference. Is this a bug?

<dtml-sendmail mailhost="MailHost">
To: 'brabander@fsw.leidenuniv.nl'
From: 'brabander@fsw.leidenuniv.nl'
Subject: 'foo'

bar
</dtml-sendmail>
