282919 - When I forward some e-mails, I get told I'm sending an illegal attachment, but not told what it is or given option to remove it

Status: RESOLVED EXPIRED

(Thunderbird :: Message Compose Window, defect)

Description

[John]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
Build Identifier: Mozilla Thunderbird version 1.0 (20041206)

When I try to forward a few particular e-mails (it does not happen on many), it
goes to approximately 74% of status "Delivering mail", then tells me "An error
occurred while sending mail. The mail server responded: 5.7.0 Illegal
Attachment. Please check the message and try again"

But when I check the message, all I see is the message that I'm forwarding, and
I get no indication of what is illegal.

When you generate this error, you should give us the option to remove all
attachments, then if that doesn't make the message too empty, we could easily
try again.

Reproducible: Always

Steps to Reproduce:
1. This is happening when I try to forward messages that came from the American
Indian More group at MSN <[e-mail]. I assume it will
happen with other "groups.msn.com" messages.
2. click FORWARD on one of those group mails
3. add text
4. click SEND
5. Usually, it gets to around 75% then gives me an error message as described above.

Actual Results:  
"An error occurred while sending mail. The mail server responded: 5.7.0 Illegal
Attachment. Please check the message and try again"

Expected Results:  
It should give me the option to delete the illegal attachment, or if it can't
tell what the illegal attachment is, to delete all attachments (or possibly give
a list of all attachments and let us choose what to delete)

Though I have found a workaround (I highlight all the text, CUT it, then PASTE
WITHOUT FORMATTING.

BUT this means that I'm not sending the nice picture that comes with the
publication.

I don't think thunderbird can do anything about this. The message you quote is
coming from the SMTP server that you're using for your outgoing mail. The
administrator apparently has a policy of rejecting certain attachments.

Tb is recognizing SMTP server is refusing to accept your message, but it has no
way of recognizing specifically that the message is being rejected because of an
attachment.

I understand from your comment that Tb does not actually understand the feedback
from the SMTP server. But would there be a possibility of having an option in Tb
to remove attachments from a message like that where we actually didn't ask that
they be attached?

Perhaps Tb could give us a list of what is attached if we were to press a
certain key, then we could delete one at a time until we were able to send the
message successfully. When trying to correct the situation manually, I'd delete
the images that I could see, and send the message again, only to get the error,
so I believe that when this happens, it's an invisible attachment causing the error.

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
