I have an email account at www.laposte.net. This is one of the few free imap
services in France, and is run by the local postal service (ie they have an good
public image to maintain and don't try dirty tricks).

Unfortunately their imap server is primarily setup as a webmail backend and has
a very short disconnect time.

I use the imap account as a roaming account and evolution is configured to move
sent mail into an imap folder on the server. What often appens is the following :

1. I launch evolution ; the imap connection is opened and I have acces to my
INBOX and various imap folders

2. by the time I've flushed my spam and found an interesting message I want to
reply to, the imap connection was severed.

3. I try to send my reply. It is moved to the local outbox, sent, then evolution
tries to move it to the imap sendbox and fails. Evolution considers the message
couldn't be send and will send it *again* every time I push send/receive.

4. Either I move it by hand to another folder, or I restart evolution. The imap
connection is live again, evolution can move the message and considers it a
success. The only downside is by this time the message was send in duplicate (or
more).

The problem is evolution considers the message wasn't send even though it only
failed to access an imap folder. It really should try to recover the connection
or move the message to a temporary local folder if this fails, sending (and
failing) all over again just do not cut it.

I'd really like this to work, right now a good archive of send mails that I can
access from everywhere is more important for me than not annoying other people.
