I had to change the smtp server to a third-party one ([mail.ru](http://mail.ru)). I’ve set everything up, but when I try to send a test letter I get this error.

What could be the problem?

Can you connect to the server from inside the container? It may be some issue with docker not being able to get to that mail server.

`./launcher enter app`

Then try the telnet command you feed before.

I found a way to fix the problem. Change the port to 587 and insert the password for the third-party application, instead of the password for the mail account
