Bug report

Bug report

Steps to reproduce

1. write an email and attach a file located on a network path (\node\share...)
2. the link is generated and inserted into the email
3. send the email

network path is a folder shared by windows 10 (from another computer in the local network)

Expected behaviour

The email is sent with a download link and not with an attached large file

Actual behaviour

The email is sent with a download link AND with the attached large file. Upload to owncloud and sharing works! The attached file is on owncloud and shared. The link also works properly. BUT: the large file is sent as an attachment. There is no indication of an error.

Using a local file as attachment works fine.

This is actually a bug of the filelink component of Thunderbird itself: https://bugzilla.mozilla.org/show_bug.cgi?id=793118

The problem occurs only when I drag'n'drop a file from a network share. If the share is mounted as the disc, or when I add a file from network share via menu, the problem does not occur.

So, a workaround is to mount the network share as a drive.
