I can't reproduce this with 20030402 on Windows and 20030331 on Linux.

Martin, would you please test this issue again with a more recent build (like 1.4a)?

Comment 2

[martin ngai]

It happened in 1.3 release version.

Comment 3

[Christian Eyrich]

And? If it's not reproduceable in current builds it's invalid. So do you can
reproduce it with e.g. 1.4a?

This should be a dupe of bug 195009 anyway.

Attachment: zip file that will corrupt

sample zip file that will corrupt itself. It is created by the windows XP
(zipped folder)

Comment 5

[martin ngai]

same behavior in 1.4a

Comment 6

[Christian Eyrich]

I can't still reproduce this problem. Would you please mail me the zip file from
the attachement from your account?

Comment 7

[martin ngai]

did you use the zip file that attached on 2003 Apr 5.  send a mail as an attachment.

Comment 8

[Christian Eyrich]

Thanks for the mail.
The difference between your mail and my tests is, that your attachment uses 
Content-Transfer-Encoding: quoted-printable
and mine
Content-Transfer-Encoding: base64

I don't know exactly if this is the reason. I think quoted-printable isn't
forbidden for attachments in general, but it seems Mozilla has problems
generating it. The mail you sent me contains tabs (\t or 0x09) right in the
encoded stream.

I didn't manage it, to send a attachment encoded as quoted-printable too. Do you
know how to change this encoding?

Comment 9

[Christian Eyrich]

Attachment: corrupt attachment

Ok ok, tabs in quoted printable seem to be allowed as I now know.
But the attachment I received is corrupt nevertheless (tried to receive the
mail with another mail app and failed). So here it is, I don't know what to do
with it.
