I did notice this problem several times before, though did not try to reproduce
it yet since I do not want to lose more mails.

I have set a size limit of 100k so that larger mails won't be downloaded completely.
Sometimes if I get a mail which is larger than that, is is erroneously marked as
spam and moved to the spam folder.
What I then do, is to mark the mail as not spam and move it to my folder for
work related mails.
Then I click on the link to download the rest of the mail. Thunderbird opens the
connection to the server and downloads the mail. But once the download is
complete, the message disappears completely and is lost forever.

I'm using the official Thunderbird 1.0 release and am retrieving my mail using POP3.

Reproducible: Didn't try
Steps to Reproduce:

My system information:
Windows XP Pro SP2
Pentium 4m 1,6GHz
512MB Ram

having the same problem... Thunderbird DELETES the mail also from the server!!!
Many e-mails lost this way...

Have the same problem because I have set up Thunderbird to fetch headers only. 
When I start to download the full message, it may vanisch completely.

It seems that this only happens, if Thunderbird tries to fetch new messages from 
the server at the same time. So I switched of the option "look for new mails 
every x minutes" to avoid such a situation. But this can only be a weak 
workaround for the problem.

My current Thunderbird is the German Version 1.0.6

I am also running WinXP Pro SP2, and have experienced this exact phenomenon.  In my case, avast pro mail scanner detected a spam e-mail with infected attachment and deleted the e-mail. I had to restart the e-mail download, and had no record of the the downloaded e-mails, and the next time I reopened thunderbird, ALL my e-mails were gone INCLUDING SENT e-mails!

This is the closest to the bug I've been experiencing.
I always telnet to the server to delete spam before downoading. 
Any mail that I read during the telnet session gets marked as read on the server, 
is not downloaded to thunderbird, but IS removed from server.

same thing here and happens alot.
this is what most people would consider to be a MAJOR bug as it looses and destroys data.
nothing done to fix this since the first post was in 2004.... 4 years is a long time.... guess we just gotta live with this LONGGGGG running problem.

Willie, you're comments, while useful in pointing out the problem still exists, don't get us further to a resolution.  what will help is a) describe the problem better than comment 0 does, b) search bugzilla to see if this problem is already reported - perhaps there is a bug which has more progress or a better description. (this sounds like a dupe)
