[sylpheed:34233] Cannot save to outbox

[Thomas Faber]

Hi everyone,

I have Sylpheed set to automatically check for new mail every
10 minutes. If I happen to send an e-mail at the point when
it's checking for mail (which takes a while; ancient ugly, slow
IMAPS server), my message gets sent, but as the IMAP connection
is busy, I receive an error telling me the message could not be
saved to the outbox. The message window is then closed.
Thus, I have sent the message, but have no record of it
whatsoever.

That is.... unacceptable to say the least.

Additionally, the message itself is confusing as "Outbox" refers
to the outgoing message queue in most programs, not the sent-mail
folder. The first few times, I re-wrote the message and was then
told by the recipient that they'd received it multiple times. (In
that case, it happened because the IMAP server was down, the SMTP
wasn't, as I recall)

Has anyone else experienced this? Or do I have a completely messed
up setting somewhere? Should be a relatively simple fix in any case.

Thanks, and a nice weekend to everybody.

Regards,
Tom
