Error in IMAP command received by server

[walrus781]

Error: Error in IMAP command received by server. i'm working with multiple mails, so i'm trying to get all boxes

var config = {
    user: email,    
    password: pass,
    host: host,
    port: 993,
    tls: true,
    tlsOptions: { 
        rejectUnauthorized: false
    },
    authTimeout: 30000,
    debug: console.log
}

let imap = new Imap(config)
imap.connect();
imap.getBoxes(function (err, boxes) {
    if (err) throw err;
    console.log(boxes)
});

that's what debug is consoled

okey, i'm just stupid, forgot about imap.once()

[walrus781]

okey, cause im working with multiple email, i'm trying to loop coming data and connect in loop, but somithing gone wrong, so i'm here again my loop

for(var i in json.data){
    try{
        if(json.data[i].settings.email_conf){
            if(json.data[i].settings.email_conf.host){
                                var config = {
                    user: json.data[i].settings.email_conf.login,   
                    password: json.data[i].settings.email_conf.password,
                    host: host1,
                    port: json.data[i].settings.email_conf.incoming_port,
                    tls: false,
                    autotls: 'always',
                    tlsOptions: { 
                        rejectUnauthorized: false
                    },
                    authTimeout: 30000,
                    debug: console.log
                }
                                let imap = new Imap(config)
                await imap.connect();
                await imap.once('ready', async function(){
                    await imap.getBoxes(async function (err, boxes) {
                        if (err) throw err;
                            console.log(boxes)
                        });
                    })
                }
            }
        }catch(e){
            console.log(e);
        }

i've added tls: false, autotls: 'always',, dunno why, but it's works, almost now i'm getting only one box from the loop there's console

then it throws Error: Timed out while authenticating with server

[mscdex]

imap doesn't return Promises from its functions, so having await is useless and could be causing problems with expectations?

[walrus781]

okey, deleted it, is still same(

[mscdex]

Are they connections to the same host?

[walrus781]

not all, mostly to justhost, but have few gmails

[mscdex]

Also, the tls/autotls settings will depend on the configuration. This is something you should be getting from your host configuration somewhere. Typically port 143 is plain IMAP (no/explicit TLS) and port 993 is encrypted IMAP (implicit TLS). You could set tls/autotls depending on the port number, but in reality any port number could be used with either kind of encryption setup.

[walrus781]

port 993 is used at all, with tls and autotls I just experimented, checked what I get

[walrus781]

that's what i'm get when config like this

var config = {
    user: login,    
    password: password,
    host: host,
    port: port,
    tls: true,
    authTimeout: 30000,
    debug: console.log
}

[connection] Error: Error: 19188:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:openssl\ssl\record\ssl3_record.c:252:
Error: 19188:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:openssl\ssl\record\ssl3_record.c:252:

As I understood it, something is wrong with certificates, but I do not know what and how to solve it D:

[mscdex]

Port 993 isn't used at all? Are the ports different for the servers that aren't working?

[walrus781]

no, port 993 in every email config which i get

[walrus781]

So, I try to go through all the mails and take unread messages, I get mail configs from a json object and go through it using for ... in. it turns out that the new cycle, a new connection to another mail from the json object. I'm trying to do about. Hope it helps to understand my problem

[mscdex]

Ok, then tls: true should be correct in that case as long as the servers are using that port number for what it's typically designated for (implicit TLS).

[mscdex]

Also, you should avoid using rejectUnauthorized: false as it's not secure. It will allow anyone to MITM your encrypted connections.

[walrus781]

yeah, i get it now, thx, but it still throws [connection] Error: Error: 16068:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:openssl\ssl\record\ssl3_record.c:252: and i already removed it rejectUnauthorized: false, thx
