392370 - message: 5.7.1 Too many MIME parts, even with small attachments

Status: RESOLVED INCOMPLETE

(Thunderbird :: General, defect)

Description

[Ronnie Tucker]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.6) Gecko/20061201 Firefox/2.0.0.6 (Ubuntu-feisty)
Build Identifier: 2.0.0.5 (20070725)

I create an email with several attachments (in this case it was ten attachments, totalling 10mb), assign a recipient then send. After a short time I get the message: 5.7.1 - Message contained too many MIME parts. We do not accept such complicated messages.
Like a previous bug I reported, I contacted my provider and they assure me of no such limits. Also when I try to send this email through Kmail it sends without a problem.

Reproducible: Always

Steps to Reproduce:
1. create email
2. assign recipient
3. choose attachments
4. click send
Actual Results:  
5.7.1 - Message contained too many MIME parts. We do not accept such complicated messages.

Expected Results:  
should send without error. Kmail sent the message with no reported error.

I'm using a standard Kubuntu Linux installation.

Like my previous bug report, if the problem was with the mail server then why doesn't it stop Kmail from sending the email?

It seems as though something is fooling Thunderbird2 into giving these error messages?...

You looks to be the opener of next thread in Mozilla Thunderbird Support forum.

Is there any evidence of "5.7.1 ... from server is caused by Thunderbird' fault"?
Are you sure that there is no setup problem or no environment problem?
Please note that here is bugzilla.mozilla.org, not support forum.

Text following "5.7.1" is one like "Relaying denied" or "Unable to relay" in many cases. The message text has no meaning for protocol, and the text is not proper  explanation of error some times.
Isn't problem of "5.7.1 Relaying denied"?

There is Bug 313036. So, if your setup contains mistake, and if your SMPT server supports SMTP server access without login, user usually can not be aware of SMTP connection with no SMTP AUTH.
> 313036 Don't fall back to no SMTP AUTH with no notification to user, if user specified 'use username and password'

An smtp log could be good to have here <http://www.mozilla.org/quality/mailnews/mail-troubleshoot.html#smtp>
