We have installed Youtrack 3.3. We are not receiving email notifications and following is the error in the logs, as well as in the "test email settings" section.
Can't send email to firstname.lastname@example.org
. Mail server connection failed; nested exception is javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 25; nested exception is: java.net.ConnectException: connect: Address is invalid on local machine, or port is not valid on remote machine
Can anyone help, please?
