Hello. I have an mail account on Zoho. IMAP works fine without any problems. But when I tried to send message throught SMTP I get "Could not queue message for sending." error message. Network log output [21:08:08] IMAP> 81 SELECT Queue [21:08:08] IMAP< 81 NO SELECT failed ** IMAP error on imap.zoho.eu: SELECT error ** can't select folder: Queue [21:08:08] IMAP> 82 APPEND Queue (\Seen) {6614} [21:08:08] IMAP< + Ready for additional text [21:08:08] IMAP> [data - 6616 bytes] [21:08:09] IMAP< 82 NO APPEND failed ** IMAP error on imap.zoho.eu: APPEND error Before it worked. Maybe this due changes on Zoho but I not sure.

It does look like a server problem.
Perhaps you previously deleted the Queue folder with another connecting client? Try rebuilding the folder tree from within Claws Mail and/or configure a different queue folder in account preferences.
