Error syncing changes: Source stream returned no data
Since a while, but at least still as of Evolution 3.42.2 I see some bigger issues with one IMAP server, that I use (which is Dovecot).
Every time I send a mail (and Evolution then tries to save it in that IMAP server's Sent folder) I get errors like these:
Your message was sent, but an error occurred during post-processing. The reported error was “Failed to append to Sent: Error appending message: Source stream returned no data Appending to local “Sent” folder instead.”.
The mail is then however found in the IMAP's sent folder (3 to 4 times)... and also in the local Sent folder.
Similarly when expunging:
Failed to refresh folder “foo@bar : Trash”. The reported error was “Error expunging message: Source stream returned no data”.
Also, accessing any remote mail (on the IMAP server) seems to run into timeouts or retries... there is no error messages, but it takes quite long.
