16:24:17.453 Warning: unhandled untagged OK with a response code
Thanks. This is a combination of a bug in Trojita (we try to
save mail into a non-existing mailbox) and a nasty bug in the
IMAP server (a synchronizing literal is not properly aborted by
sending a tagged response).
In baseline IMAP, clients have to "ask" the server for
permission before they send large chunks of data (in this case,
the content of the outgoing mail). A server is supposed to
ackowledge its willingness to accept these data by a command
continuation request, or deny it by sending out a tagged NO or a
tagged BAD. In this case, the server should have said something
like this:
y11 NO [TRYCREATE] Must create mailbox before append
What happens in this case is that Trojita gets stuck waiting
for either this tagged NO or BAD, or for a command continuation
request ("+ go ahead, send us the data"). It is the server's
fault that it does not send this response as a tagged one. Even
if Trojita recognized this untagged OK [TRYCREATE] (which is in
itself a bit hard because these command could theoretically be
pipelined in parallel) and detected "ah, OK, this command will
fail", the server still must respond to our command with a
tagged response. Right now the server believes that the command
was handled, while Trojita gets stuck waiting for something
which is not going to come.
OK, got it; thank you very, very much for your the detailed explanation!
You can "fix" this by creating a mailbox names "Sent", or
changing Trojita's settings so that it uses another mailbox for
saving mail (or even unticking that checkbox for saving outgoing
stuff in the first place).
Do you know what IMAP server implementation is that?
No, I don't. It's the "stock" IMAP server offered by my ISP. I tried using
the "IMAP Server Information" menu item but it says that the server has not
provided information about its software version :( It only lists the
supported capabilities.
Thanks again for your help! Trojitá rocks :-)
Best,
George
