jakarta.mail.AuthenticationFailedException with valid credentials

[Tasza33]

Hi community. I'm trying to send email without SSL through that repo, in which your methods are used. So my config there looks like:

\"mail\": {
        \"host\": \"mail.com\",
        \"port\": \"25\",
        \"username\": \"[email protected]\",
        \"password\": \"${CI_EMAIL_PASSWORD}\",
        \"securityProtocol\": \"null\",
        \"from\": \"[email protected]\",
        \"recipient\": \"[email protected]\"
  } 

My credentials are valid, that was tested. Maybe you know what's going wrong?

Most likely it is this issue: javax.mail.AuthenticationFailedException: 535 5.7.3 Authentication unsuccessful which is issues with exchange permissions or unable to relay messages from the account you are using.
