Steps to reproduce:

I have dramatically growing mailfiles for subfolders in an IMAP account
This is happening under 16.0.1 under kubuntu. The server appears to be running 
dovecot:

openssl s_client -connect myhostxxxx.webpack.hosteurope.de:993
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE 
AUTH=PLAIN AUTH=LOGIN] Dovecot ready.

It was also reporting individual mails with larger (2-5MB) attachments
as only having a few (20-30) kb, so my guess is something to do with
attachments. Running a repair on the folders fixed it (see below)

I am using this account from a server and a laptop. This may have
started when I set up the subfolders (on the laptop as I was traveling)
and moved mails into those subfolders. There are two thunderbirds
accessing the account at the same time, the server and the laptop (both
kubuntu with 16.0.1). The size explosion is happening on the server, and
not on the laptop.

I ran out of disk space on /home twice before I saw what the cause was... seems 
to be as described in bug #463359
I also saw the symptoms as mentioned in bug #802217 with those two folder being 
continually refreshed (Downloading message x/x in folder1).

Also saw this in the Inbox and Sent folders this morning, repairing them
fixed the problem- the individual mails had the right size, and the
mailbox (which was huge but underreporting its size in the folder pane)
as well.

A number of us are seeing this problem in our organization.  Compacting
the mailbox is a temporary fix, but it starts growing again immediately.
My INBOX is ~80MB when compacted.  Grew to 20GB over a few hours.

I'm seeing it again as well on a second machine (laptop accessing the
same IMAP account and folders). Inbox reports 6MB with 43 messages...
only 4-5 above 500kb (so the summed size in the folder display is
consistent with the individual mail sizes _reported_ in the message
list). On disk the Inbox has 230MB. And individual mails that have
attachments report their size (correctly) in the attachment list at the
bottom as 3-4 MB, but are listed as 30kb in the message list.

I have a feeling that this might have something to do with the mail
having a graphic in the signature, and separate attachments, but I'm not
sure. Those mails are coming from Outlook. I'm fairly sure that this
didn't happen with TB15, but not 100% sure.

Bug 803326 may be the same issue. Launchpad has the mailfile size bug

I created the report on launchpad.
I'm also connecting to webpack.hosteurope.de
A co-worker reported he also has the issue with another mail provider. I can 
try to find out what that server is running in order to know if it's related to 
the server connecting to.

It's also running dovecot (dovecot-imapd 1:1.0.15-2.3+lenny1)

I won't get the chance to do logging in the next few days, but if
someone could, that would be great:

export NSPR_LOG_MODULES="imap:5,ImapAutoSync:5,mime:5,mgsdb:5,timestamp,sync"
export NSPR_LOG_FILE=/tmp/tbird.log

See https://wiki.mozilla.org/MailNews:Logging for more info.

Title:
  Mailbox grows endlessly, heavy traffic

Status in Mozilla Thunderbird Mail and News:
  New
Status in “thunderbird” package in Ubuntu:
  Confirmed

Bug description:
  Yesterday I noticed that my Internet connection keeps transferring a lot of 
data. After a while I checked with nethogs and discovered this was caused by 
Thunderbird.
  Today I got a warning that my HDD was near full.
  In this 2 days, the mailbox had grown to 20 GB, while in reality it should be 
around 1 GB (a fresh zipped backup has 600 MB).

  I removed the .thunderbird folder and configured my IMAP mailbox from 
scratch. The same happened again.
  I think this is not related to a somehow special configuration of my PC bcs 
my colleague discovered it's the same on his machine. Without checking, he 
wouldn't have noticed yet bcs of a much bigger HDD...

  We couldn't yet find out what exactly happens / which data is transferred 
again and again.
  I suspect it's related to the last thunderbird update.

  Ubuntu 12.04
  Tunderbird 16.0.1+build1-0ubuntu0.12.04.1
