User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36 Steps to reproduce: Sending an email with account configured as IMAP server with high load and/or poor connectivity, preferably with attachments. Actual results: Message is sent, but on copying the sent message to "sent"-folder, the following message pops up: "There was an error saving the message to Sent. Retry?" Retry/Cancel There's no way to save the message locally for later synchronization. Cancel means that the message will probably be lost (though it might have been sent before). This issue seems to be present at least since version 15. Expected results: Giving the option to save locally for later synchronization, when the IMAP server is reachable again.
