attachments | model agnostic modular framework for handling file | Application Framework library

Seems like you already have the part where you are extracting the attachments. Try this code to retrieve the body of a multipart email.

You may have to figure out how to merge your part with this one.

You can do this as a reduction over foldernames using getattr to dynamically get the next attribute.

You must be sure there are no invalid characters in the filename. See What characters are forbidden in Windows and Linux directory names? for more information. So, I'd suggest using the Replace method available in VBA before passing anything to the SaveAs method.

Another point is that you need to specify unique file names to each email. Make sure the generated file name is unique for a folder.

Here I'm wondering about the line [in s_client]
New, TLSv1/SSLv3, Cipher is ECDHE-RSA-AES256-GCM-SHA384

You're apparently using OpenSSL 1.0.2, where that's a basically useless relic. Back in the days when OpenSSL supported SSLv2 (mostly until 2010, although almost no one used it much after 2000), the ciphersuite values used for SSLv3 and up (including all TLS, but before 2014 OpenSSL didn't implement higher than TLS1.0) were structured differently than those used for SSLv2, so it was important to qualify the ciphersuite by the 'universe' it existed in. It has almost nothing to do with the protocol version actually used, which appears later in the session-param decode:

You have 2 questions that I'll answer separately.

Why doesn't the size of the message shrink after I remove the gif attachments?

MIME can contain nested multiparts and in your case, it likely does because HTML mail with images are often within a multipart/related which is often within a multipart/alternative, like this:

I'm curious. Why did you think none or all would match only messages with attachments?

As @triplee says, there's no real definition of attachment so you'll have to fix a definition yourself. But you could approximate, and e.g. move all multipart messages, or all messages with image parts, all messages with PDF parts or all messages for which a bodypart has been explicitly labelled as an attachment (which happens now and then). The search keys are, respectively, header content-type multipart, header content-type image/, header content-type application/pdf and header content-disposition attachment.

The first of these four examples will work well, the other three will work with some servers but far from all, because the specification says "…has a header with…", which one may take to mean "among the message headers" or "among either the message headers or the per-part headers". Good luck with your server.

You can also use or to join several of the conditions.

You should be able to add the cc in the options object.

It's this typo:
