sending mails failed with TLS issue after last update

 

Since some days (as far as I can see after the last uddate build 3800 or 3802) I got the following error when I try to send mails via Meta trader 5:


2023.06.17 07:39:15.704 MailDispatcher email 'MetaTrader 5 IC Markets EU email test' failed [ 5.7.3 STARTTLS IS REQUIRED TO SEND MAIL [BN8PR12CA0022.NAMPRD12.PROD.OUTLOOK.COM 2023-06-17T05:39:15.693Z 08DB6E6D4CBBEA8F], server error code [451]]



The configured mail server is smtp-mail.outlook.com:587

Before it worked without issues on this server.

The mail server supports STARTTLS:

Com:587 in mt5 and the sending of emails was working and today it stopped working. Open mt4/5 >> tools >> options >> email tab and you fill in the necessary details for your email and server, in order to receive your email notifications
