"----boundary..." is a part of the attachment

[nnnicolay]

This was reproduced with the latest version 6.1.0

Describe the bug
The attachment is saved with the wrong name, without file extension, and with "----boundary..." inside

Code to Reproduce
To reproduce the problem please use this EML

fake.eml.zip

Screenshots
I assume that the problem could be caused by incorrect parts detection when we have a nested 'boundary'. This is what we can see inside the Attachment

Additional context
The attachment name and the content

Thank you

Hello @Webklex, were you able to reproduce the problem?

[mrhewitt]

Same issue as I just report in #582

PR in #455 and commit fad09ad altered Structure::parsePart so it only handles multipart blocks with more than one part, in a case of a single part it falls through and assumes it just a single text block

Hence your content is the actual part and your filename/name is set to be the generated hash as it could not find name headers as it did not actually returned a raw block.

Will try to validate the fix

@mrhewitt Still doesn't work for my case.
But it works on https://github.com/inFreeRED/php-imap

One more issue with boundary

When at the end of the line there 2 spaces

Content-Type: multipart/mixed; boundary="--=_Next_Part_04_Jun_2025_12.10.44"
