Error: Failed to fetch all new messages

#2179

For some mailbox, e.g. deleted messages, I have the following error showing up every now and then:
"MailMate encountered the following error: “Failed to fetch all new messages in “Deleted Messages”.”. Mailbox: “Deleted Messages”."

If I move a message to deleted messages from the mail provider's web interface and then empty the deleted messages mailbox, the warning goes away, but the log still shows a similar error:

    The MailMate behavior appears to be correct. In the first case, the server tells MailMate that mailbox has 1 message:

    S: * 1 EXISTS

    But when MailMate tries to get data about this message then nothing is returned. MailMate reports this to the user. In the second case, the server reports 0 messages:

    S: * 0 EXISTS

    Which is fine. In this case MailMate shouldn't really try to fetch data (I can change that), but it's not illegal and the server has a sensible response.

    The responses of the type,

    S: D11 OK Mails not exist!

    are not a problem. The server says OK and the rest is ignored (it is for human eyes only).

    You can contact the IMAP provider to let them know about the IMAP bug.

    For the record, I've changed the behavior for empty IMAP mailboxes in the next update. (It does not solve your issue, but it would make the output in the empty mailbox case a bit simpler.)
