230830 - two null caracters (\0\0) at the end of a message block pop3 process

Status: RESOLVED DUPLICATE of bug 223062

(MailNews Core :: Networking: POP, defect)

Description

[Victor STINNER]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5) Gecko/20031107 Debian/1.5-3
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5) Gecko/20031107 Debian/1.5-3

Today, when I would like to check for news mail (and download) them, my Mozilla
downloading process blocked. I deleted popstade.dat (in my
~/.mozilla/.../pop.haypocalc.com/ directory), and retryed to download email. The
email number 11 caused problem.

So I check the email with SquirrelMail (a good webmail) : Mozilla shows my that
the message ends with two null caracters (ascii code 0, twice).

Finally, I downloaded the email using telnet (telnet popserver 110 | tee email).
You can find it, gziped, at :
http://www.haypocalc.com/tmp/email_bug_mozilla.txt.gz

Note: In shell, you can write a null caracter with CTRL+ALT GR+@ (ascii 0 is ^@)

I don't know if the bug can be reproduce every time because it is the first time
that I receveid an email with \0\0 at the end ...

Note: Mozilla Mail isn't blocked, just pop3 downloading and my Inbox folder. But
when I restard Mozilla, the folder is still blocked (and downloading process).
The solution is to delete popstate.dat file.

Bye,
Victor STINNER

Reproducible: Always

Steps to Reproduce:
I try to send me an email with null caracter, but SMTP deleted my \0\0 caracters
... You can try with your STMP server :

With telnet :
---
1. in shell # telnet smptserver 25
2. in telnet # mail from: [e-mail]
3. in telnet # rcpt to: [e-mail]
4. in telnet # data
5. in telnet : write a test email, and write null caracters at this end (press
CTRL+ALT-GR+@, ASCII 0 is ^@)

In Mozilla :
1. First, write your email with another software. Try Unix cat :
   o cat >email
   o begin
   o (something)
   o end
   o ^@^@
   o
   o
2. Open your email with Mozilla Navigator
3. Write a new email and copy the text of the file from the Navigator (to copy
null caracter)


Expected Results:  
Mozilla Mail pop3 code should replace \0 with space (' ') for example.
