I've noticed that I occassionally receive inline attachments (usually in ZIP format). These files come via e-mail (Internet) and the message header definitely indicates "attachment". Is the mail handler not able to understand the attachment being inline or is the data received not formatted correctly?

Here's the relevant header data:

OtherHeader Content-Type: application/zip;
name="google.com!caughtinadream.com!1611014400!1611100799.zip"
OtherHeader Content-Disposition: attachment;
filename="google.com!caughtinadream.com!1611014400!1611100799.zip"

Thank you in advance!

Only multi-part MIMEs are decoded internally by SBBS today. If you can send me a message with an attachment in that format, I can work on decoding support.

Thank you, sir. I'll send it over to you right away.

Since you forwarded from the msg/file from sbbs, and sbbs doesn't recognize that MIME-encode type, it didn't work. Your text and the ZIP file were all combined together into the single-part MIME contents (which fails zip integrity checks of course).

I e-mailed you a .txt version of the file. If you still don't get it, I'll figure something else out.

It arrived it as a multi-part MIME attachment, but I still think I got it sorted out. I just made a commit for you to test and provide feedback on. It won't help with your already-received messages, only newly received ones.

Good news, I hope. When going through my e-mail, the message does not freak out the display and instead shows a blank area. When choosing to download the message, it opts for download the message as text and again for the download piece (the ZIPfile). The zipfile does show some corruption, but this could be because it was from earlier today before I updated with the latest commits.

Here's the output when trying to extract the ZIPfile:

End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of 1611187199.zip or
1611187199.zip.zip, and cannot find 1611187199.zip.ZIP, period.

Mind you, this is being done on a Mac so things may be worded, well, poorly. :)

Ultimately, I will wait for my next inbound multipart message and let you know.

Single-part, but I get your meaning. Looking forward to the test results.

Yes. It's Thursday. Brain is starting to shutdown.
