Hi all, I have turned to the list before about this problem, but without success. I thought I had created a workaround, but in the end it appears I cannot do without the sendmail tag. I have upgraded from zope version 2.4.3 to 2.5.1. on a production server. I can't go back so I am really stuck. The following code in a dtml method works on 2.4.3 but produces a attribute error with value "sendall' in 2.5.1 (traceback see below) <dtml-sendmail smtphost="fswrul.fsw.leidenuniv.nl"> To: brabander@fsw.leidenuniv.nl From: brabander@fsw.leidenuniv.nl Subject: 251 groeten van 251. </dtml-sendmail> I have tried all kind of suggestions I received before, like removing spaces between the headers, using the ip address in stead of names, using a mailhost object, using mailto and mailfrom in the tag, all to no avail Traceback (innermost last): File E:\zope\251\lib\python\ZPublisher\Publish.py, line 150, in publish_module File E:\zope\251\lib\python\ZPublisher\Publish.py, line 114, in publish File E:\zope\251\lib\python\Zope\__init__.py, line 159, in zpublisher_exception_hook (Object: mailtest) File E:\zope\251\lib\python\ZPublisher\Publish.py, line 98, in publish File E:\zope\251\lib\python\ZPublisher\mapply.py, line 88, in mapply (Object: test) File E:\zope\251\lib\python\ZPublisher\Publish.py, line 39, in call_object (Object: test) File E:\zope\251\lib\python\OFS\DTMLMethod.py, line 127, in __call__ (Object: test) File E:\zope\251\lib\python\DocumentTemplate\DT_String.py, line 473, in __call__ (Object: test) File E:\zope\251\lib\python\Products\MailHost\SendMailTag.py, line 116, in render (Object: fswrul.fsw.leidenuniv.nl) File E:\zope\251\lib\python\Products\MailHost\MailHost.py, line 156, in send (Object: ) File E:\zope\251\lib\python\Products\MailHost\MailHost.py, line 201, in _send (Object: ) File E:\zope\251/bin/lib\smtplib.py, line 466, in sendmail File E:\zope\251/bin/lib\smtplib.py, line 316, in ehlo File E:\zope\251/bin/lib\smtplib.py, line 247, in putcmd File E:\zope\251/bin/lib\smtplib.py, line 235, in send File <string>, line 1, in sendall AttributeError: (see above)
