The pane showing the message content only shows some of the mail source code. I think further investigation is needed, sadly I'm not able to reproduce this, but is seems that once the message has been downloaded, it's always displayed in that fancy way. As you can see from the screenshots, Gmail webmail displays it correctly, so it must have get corrupted when downloaded by Thunderbird: http://www.imagesticky.com/images/m6tpx848n5k06vk1cq3.png http://www.imagesticky.com/images/fe7dxbyos1t79y8vmujs.png Examining the source code, I think something's wrong: part of the email source stays BEFORE the header information (see attachment). Could this be the cause of the rendering problems? Reproducible: Couldn't Reproduce
I just tried 3.1 alpha1, same problem (because the message source is corrupted, so 3.1 can do nothing to fix it). Rebuilding the IMAP folder index worked, now the message is displayed correctly, so I think it's definitely Thunderbird that messes up the source while downloading the message source. Perhaps it uses chunks and sometimes doesn't re-order them correctly?
It's difficult to tell without knowing the details of Thunderbird's interaction with the server. I'm not sure if a protocol log would help here (https://wiki.mozilla.org/MailNews:Logging), but it's worth a shot -- obviously, the tricky bit would be capturing a log at the right time, i.e., when Thunderbird is downloading a message that later turns out to have corrupt header information.

If you think it can help, I could try. I don't know this mechanism and how it works, do I have to install something/have something running in background?
It's probably not helpful unless you can recreate the problem of downloading a message and having it not display correctly.
No, I can't reproduce it. It happened to me 3-4 times until now (started having this problem with version 3.0), and always with mails that have nothing to do with each other (same sender or subject or ...). It seems unpredictable to me :(
This could happen if your mbox file is corrupted, try to rebuild index, this is may root of your problem.
(In reply to comment #7) > This could happen if your mbox file is corrupted, try to rebuild index, this > is may root of your problem. This was done, and solved the symptoms of the problem; the root cause, though, is difficult to find (as bienvenu and I noted). Without reliable repro, there's not much anyone can do here, so we'll have to wait for a bit of luck.

Just in case you are able to start reproducing this, the instructions are at the linked page -- nothing needs to be installed, but you'll have to start Thunderbird differently. Note that the log is likely to be rather large (i.e. several megabytes at least); the smaller a time window around the download of a corrupted message the better.
Andrea, you might to prepare by turning on logging by default (or at least test to see that you can set it up correctly). right click on Computer (in desktop or start menu) properties advanced environment settings system variables new set variables per https://wiki.mozilla.org/MailNews:Logging#Environment_Variables_to_set OK, etc. now logging will happen for every thunderbird startup. not likely to noticeably impact performance - I've even had it enabled on laptops.
Ok, I've set it up with NSPR_LOG_MODULES set to "imap:5" Are there other modules/logging levels I should set?
(In reply to comment #10) > Ok, I've set it up with NSPR_LOG_MODULES set to "imap:5" > Are there other modules/logging levels I should set? no, just imap. please base your results on using version 3.1, preferably 3.1.2 or higher.

This issue never happened to me again, so maybe the index file got corrupted for other reasons.
