How to send mail with attachments in Plone using a template approach?

问题

I've been reading the official docs about sending emails from Plone using some templates, and it's working so far.

My question is: how do I add attachments using the template approach?

回答1:

The MailHost.send command takes both python (unicode) strings and email.Message objects. That means you can use the python email package to construct a proper MIME message with attachments.

The standard library includes a great page of examples; any text can still be generated by templates just like in the documentation you linked.

回答2:

Use Python's email module.

Examples:

http://docs.python.org/library/email-examples.html

The composed messages can be passed to context.MailHost (the MTA of Zope).

It is in every case better generating and sending out emails from the Python level instead of using the old DTML sendmail facade...don't use it.

This is my solution, maybe it is not the best:

create a mime_file DTML Method in portal_skin/custom:

  <dtml-mime type="text/text; charset=utf-8" encode="7bit">

  <dtml-var "text">

  <dtml-boundary type="application/octet-stream" disposition="attachment" 
  filename_expr="nomefile"><dtml-var "file"></dtml-mime>

Call it (for example from a Python Script) as:

message = context.mime_file(file=a_file, text=message, nomefile='attach_name.pdf')
context.MailHost.send(message, mTo, mFrom, mSubj)

where a_file is the content of the file.

inspired by:

This is a quick&dirt solution, using Python Scripts.
