Description Francis 2015-09-17 07:40:32 UTC 
This happens on a specific IMAP server, I can't reproduce it on my IMAP GMAIL account for example.

Here's the procedure to reproduce it:

  1. Create a folder in INBOX/Travel/Misc
  2. Put an email in that folder
  3. Move the folder 'Misc' in INBOX/
  4. 'Misc' still contains the email
  5. Move back 'test' folder in INBOX/Travels/
  6. 'Misc' folder is now empty :-/

I attached the logs corresponding to step 5.

From the logs one case see:
** IMAP error on gwmail.xxx.com: protocol error(very probably non-RFC compliance from the server)
** IMAP4 connection broken

which suggests that there's something wrong on the server side or something not supported.

If it's really the case, I think Claws should do the necessary for trying to make it works in order to support such (broken) servers. Or at least reports the error to the user and do *nothing*.

But in any cases, it should LOST emails SILENTLY.

BTW Thunderbird chooses to work perfectly fine here.

This affects Claws 3.11 as well.

I already reported it on Claws' mailing list but it didn't get any attention althouth it's a critical bug IMHO specially when emails are lost !

Here's the log from "claws-mail --debug" when doing the following step:

  1. a folder INBOX/lists/test contains 1 email
  2. Move the folder 'test' in INBOX/
  3. INBOX/test folder still contains the email
  4. Move back 'test' folder in INBOX/lists/
  5. INBOX/lists/test folder is now empty :-/
