Hi,
two fedora users has found there are compression failures when cyrus-imapd
(2.3.15) is communicating with thunderbird 3.0 (this is first version
supporting compression). Does anyone have seen this?
Cheers,
Michal Hlavinka

Note that this only affects
auto-saving of messages into "Drafts" or copying sent messages into the "Sent"
folder.
This happens most often when sending emails with large binary attachments
(e.g.
.docx files).
The odd part is that the process that was previously connected to will exit,
and my UA (Thunderbird) will tell me that there was an error ("I/O Error") and
ask me if I want to retry.
Clicking OK will cause it to connect to a freshly spawned process and succeed.
If I had to guess, I would conclude that over time, the client and server ends
get out of sync (and therefore, agreement about connection state) and the
server process exits. When a new process is created and its state
initialized,
the client and server processes once again are in agreement.
How to reproduce:
Configure TB 3.0 to have an IMAP/S connection to a server running Cyrus
2.3.15. Enable auto-saving of messages. Configure to save sent messages in
the "Sent" folder on server.
Create a message, and attach a Word document to it. Send it.
