SMTP and logs

[compilando]

I'm trying to configure / debug SMTP mails. All is ok with the documentation (and with the rails documentation), but I found hard to debug.

No error is show in log/web-puma/current about the smtp send process, and I can't find easily what rails config I have to modify to increase the log level. So I don't have too mucho info about the smtp send process and errors...

Kind regards
