Error message upon "Expunge": The IMAP server sent us a reply which we could not parse. This might either mean that there's a bug in Trojitá's code, or that the IMAP server you are connected to is broken. Please report this as a bug anyway. Here are the details: UnrecognizedResponseKind: -1 * -1 RECENT ^ here
Thanks. This is a bug in your IMAP server (Zimbra, right?). Please report this issue to them. If this isn't solved by a reconnect, please reopen this with full a IMAP protocol trace (IMAP -> Debugging -> show IMGP protocol log). If it's just a transient error, though, I would prefer to leave this diagnostics as-is.
