1867984 - mail attachment not forwarded, attachment size unknown

Status: RESOLVED DUPLICATE of bug 408114

(Thunderbird :: Untriaged, defect)

Description

[Djfe]

Attachment: mail.eml

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:122.0) Gecko/20100101 Firefox/122.0

Steps to reproduce:

received a mail and then tried to forward it (attached mail.eml)

Actual results:

the attached .odt file is not part of the message (body) of the forwarded mail.

in-case this is relevant:
Thunderbird lists the file and says "file size unknown" ("Größe unbekannt" in German)

Expected results:

The .odt file should be attached to the forwarded mail.
Just like for other mails with attachments. This is the first mail I encountered where forward doesn't forward the attached file and I don't see what causes this.

The e-mail has an incorrect MIME structure, the attachment is in the multipart/related section. Duplicate of bug 408114.
