Re: Move mails between folders on different backend servers – Problem with Horde Webmail

    Hello,
    as we're facing more problems
      (something with uidvalidity …) with cyrus-imapd-3.2.6 and
      Horde/IMP Webmail: Is anyone using this combination?
    

    Thanks,

      Frank

    
      Hello,

        we have a traditional murder (frontend with 2 backend servers –
        cyrus-imapd-3.2.6-Debian-3.2.6-2+deb11u1).

        We use shared folder (group namesapce).

        Moving e-mails between folders on different backend servers
        (from backend1 to backend2) works with Thunderbird, alpine etc.
        With Horde Webmail there is an error, see below.
       IMAP logs:

      
      OK:                                                                           
         

        Frontend:

        <1648127917<6 UID MOVE 855056 group.fritest2

        >1648127917>* OK [COPYUID 1647952540 855056 11]
          Completed

        
        Backend (same source and target)

        <1648127917<6 UID Move 855056 {14+}

        >1648127917>* OK [COPYUID 1647952540 855056 11] Completed

        
        NOT OK:

        Frontend:

        <1648127910<6 UID MOVE 855054 group.fritest

        >1648127910>6 OK [COPYUID 1611826992 15] Completed

        
        Backend (source):

        <1648127910<6 Uid Fetch 855054 (Flags Internaldate)

        >1648127910>* 1981 FETCH (FLAGS (\Seen $Label4 NonJunk)
        UID 855054 INTERNALDATE "23-Mar-2022 19:55:11 +0100")

        6 OK Completed (0.000 sec)

        <1648127910<PROXY2 Uid Fetch 855054 (Rfc822.peek)

        >1648127910>* 1981 FETCH (UID 855054 RFC822 {3129}

        Return-Path: …

        PROXY2 OK Completed (0.000 sec)

        
        Backend (target):

        <1648127910<6 Append {13+}

        group.fritest (\Seen $Label4 NonJunk) "23-Mar-2022 19:55:11
        +0100" {3129+}

        Return-Path: …

        >1648127910>6 OK [APPENDUID 1611826992 15] Completed

        <1648127910<Q01 LOGOUT

        >1648127910>* BYE LOGOUT received

        Q01 OK Completed

      
      So the responses on COPYUID are different. 

      
      When moving between different backend servers, Horde Webmail
        throws warnings and errors in its log file:
      2022-03-24T14:18:30 WARNING: HORDE: [imp] PHP ERROR:
        array_combine(): Both parameters should have an equal number of
        elements [pid 64686 on line 4905 of
        "/usr/share/pear/Horde/Imap/Client/Socket.php"]

      
      PHP source is:
       
             case 'COPYUID':                                                                                                                                                                                  
            // Defined by RFC 4315
            // COPYUID: [0] = UIDVALIDITY, [1] = UIDFROM, [2] = UIDTO
            $pipeline->data['copyuid'] = array_combine(
                $this->getIdsOb($rc->data[1])->ids,
                $this->getIdsOb($rc->data[2])->ids
            );

      So the IMAP client in Horde expects 3 values for COPYUID
        response (and doesn't handle if there are 2 values only – it
        throws errors in the following processing).

        
        Is cyrus-imapd wrong in this case returning 2 values only
        (missing the source UID of the moved message)? 

      
      Thanks,

        Frank
