[Bug 94357] Sending a attachment with a long filename is goes horribly wrong

Sending a attachment with a long filename is goes horribly wrong

Hello, I have been working on a big issue with sending email form Thunderbird to:
squirrel mail, outlook express, horde and maybe other clients.

While I send a file with a long filename the attachment will not arrive
successful by the recipient the filename will be lost but mine type will
be correct. In outlook express this mean the file will be renamed to
something like D234234.dat a binary file.

I have attachment two documents they are the same but one with a short
name and one with a long name. If you send those with Thunderbird to a
other client it will go wrong. But in Thunderbird everything seems to go
fine.

Also when I sent the same files with squirrel mail, horde, claws mail or
outlook the file will be received successful by the recipient.

I have to mail a lot to persons with outlook clients and I have been
pulling my hair out why they did not receive my mail attachments
correctly.

This tells me there is a probably a big problem with the way the
standards are implemented in Thunderbird.

Please fix this bug, so I can safely send mail again to the rest of the
not Thunderbird client using world. :-D
