Problem sending mail

[Consul]

Greetings to all. I had the following problem. I'm trying to use mailwizz + pmta.
In PMTA I use port 2527. When configuring the delivery server, I also specify port 2527.
When I try to add a delivery server and verify it, I get the following error:
1) If I use the Default system mailer - Swiftmailer
Can not send the confirmation email using the data you provided.
Here is a transcript of the error message:
Failed to authenticate on SMTP server with username "name@domain.com" using 1 possible autenticators
2) if I use the Default system mailer - Phpmailer
Cannot send the confirmation email using the data you provided.
Here is a transcript of the error message:
SMTP Error: Could not authenticate.
SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting
Connection: opening to domain.com:2527, timeout=30, options=array ( 'ssl' => array ( 'verify_peer' => false, 'verify_peer_name' => false, 'allow_self_signed' => true, ),)

When using Microsoft Outlook 2010, there is no problem. When configuring Microsoft Outlook 2010 I also specify port 2527. Letters go, and an unencrypted connection is used.
Perhaps this is the problem. How to decide I do not know.
Please help.

I tried to change the protocol. Left as in the picture, and then tried the remaining options. It did not work.

try protocol STARTTLS
open firewall port 2527
double check password

 

[Consul]

try protocol STARTTLS

• Connection could not be established with host smtp.domain.com [Unable to find the socket transport "starttls" - did you forget to enable it when you configured PHP? #0]
  Log data:
  ++ Starting Swift_SmtpTransport
  !! Connection could not be established with host smtp.domain.com [Unable to find the socket transport "starttls" - did you forget to enable it when you configured PHP? #0] (code: 0)

double check password

The password is correct - 100%.

try only alphanumeric pwd

That might be it, sometimes when the password uses special chars there will be some login issues.
