Cannot connect to external SMTP server

I have setup an SMTP server (ie server #2) in another domain and it's running PowerMTA with 10 ip addresses.

Using Mailwizz in server #1 I tried to connect, but it can't be done.

Error message:

Connection could not be established with host xxx.xxx.xxx.xxx [Connection refused #111]
Log data:
++ Starting Swift_SmtpTransport
!! Connection could not be established with host xxx.xxx.xxx.xxx [Connection refused #111] (code: 0)

I tried using domain name and IP address but it cannot work.

Any help?
 
I've been reading but I'm sorry I still can't get it to work. Is it a configuration on my mailwizz server or the SMTP server?
 
OK, I've tried different approach by using port 587.

I use port 587 and TLS protocol and it seems to connect but with the following error:
<< 220 server.xxxxxx.com ESMTP Exim 4.89 Tue, 12 Dec 2017 00:23:04 -0500
>> EHLO yyyyyy.com
<< 250-server.yyyyyy.com Hello server.xxxxxx.com [117.53.155.201]
250-SIZE 52428800
250-8BITMIME
250-PIPELINING
250-AUTH PLAIN LOGIN
250-CHUNKING
250-STARTTLS
250 HELP
>> STARTTLS
<< 220 TLS go ahead
!! Unable to connect with TLS encryption (code: 0)

If I use port 587 without protocol I get the following error:
Failed to authenticate on SMTP server with username "pmta" using 2 possible authenticators

So technically it's all OK if I use a different port?
 
OK I found the issue. I ask my host to open up the port and it's done. Basically my programmer setup a port number on my SMTP server but this port is blocked by my host. So once they open it, it's all done.
