Hi,
we are having problems with sending emails via an SMTP relay with no user and password required. i am able to send emails to the relay using mailx / sendmail.
those are the settings.
DISCOURSE_SMTP_ADDRESS: xyz.example.com (obfuscated)
DISCOURSE_SMTP_PORT: 587
DISCOURSE_SMTP_AUTHENTICATION: plain
what I get back, when using the discourse_doctor is giving this error.
Net::ReadTimeout
it appears to me like the SMPT message sent is mal-crafted as we send stuff, but we do not get anything back on port 587. this is provable with a Wireshark trace.
can you please elaborate how to put more verbose logging or additional debugging so we can further analyze the problem? the regular logs don’t tell me anything. i found backtrace, but I am not a ruby developer so cannot interpret this.

I downgraded the application to the latest stable release, which did not solve this problem. the guy working on this before is on PTO, so I cannot tell to which version this was before the latest update happened. I also realized, there were recent code changes in the mail area. maybe problems there ?
thank you
