SMTP Fails

[Philippe Langevin]

Hi there !

I'm currently testing Review Board and I cant make the whole email thing to work at all.

I've setup three other tools without problems but they are all on Windows (I run ReviewBoard (w PowerPack) on the bitnami image for tests).

The Mail Server we have is only an SMTP relay without the need to have a username password.

When I try to send the test EMail (In the E-Mail Settings page) or a "Review Created" Email, I have the following log:

2019-06-14 22:38:47,059 - ERROR -  - root - Failed to send test e-mail.

What show I check next ?

Thank you

It's not reviewboard issue. It seem that remote SMTP relay closed the connection. From that server where RB is installed try to send an email from shell using same relay with mailx or whatever.

in smtplib you can also set debug level to 1 to see actual smtp dialogue set_debuglevel(1) is the method.
