Hello. Many thanks to all for your answers on my recent question about MIMETools. Really, tag <!--#boundary --> is implemented now, and works, but... I need sending mail with multiple file attachement... Combination of several tags <!--#boundary --> working... When I tryed insert tag <!--#boundary --> into tag <!--#in -->, Zope said: "Unexpected tag, for tag <!--#boundary ..." Because <!--#boundary --> is only meaningful in the context of the <!--#mime --> tag. We have loss of this context? Below example of my stupid code. [ --- begin code snippet ---] <!--#mime type=text/plain encode=7bit --> just example text... <!-- #in "files_to_mail" --> <!--#boundary type=application/octet-stream disposition=attachment encode=base64--> <!--#var sequence-item --> <!-- #/in --> <!--#/mime --> [ --- end code snippet ---] Any ideas? Dima.
