Hi all, and apologies if this is similar to some of the other posts that mention this error. For the last four days all emails have stopped getting sent, and the test email also fails. I have browsed through existing topics that are similar, but in my case nothing (that I am aware of) has changed,…

Follow [Bild] Discourse SMTP sends "EHLO localhost" instead of domain, breaking Google smtp-relay bug Can you please try adding a new line with DISCOURSE_SMTP_DOMAIN: conversation.sevarg.net and try again? Fill the new env var with your email domain and rebuild.

I have no useful advice yet, but have run into exactly the same issue, with exactly the same setup - DigitalOcean droplet, sending email via smtp-relay.gmail.com , getting EOFErrors. Sidekiq reports the following: Jobs::HandledExceptionWrapper: Wrapped EOFError: end of file reached Looking in /log…

Well, it’s definitely a comfort to know that my set up is not too uncommon, and that I am not alone in my woes. Curious, did the problem start about 5 days ago for you as well? Maybe there was an update to something common in our pipelines. Thanks for sharing the details, and back trace. Mine were …

The first real spike in failures in Sidekiq was Jan 14, so… 5 days ago. Before that, I had some random failures related to bad emails or such, but nothing ticking up rapidly. I tried recreating the relay settings in the Google Admin Console and fiddling with those (including what should be wide op…

Another report of issues, DigitalOcean → smtp-relay.gmail.com [Bild] Gsuite smtp-relay issue "end of file reached" support Forgive me if this is covered somewhere else. For the past couple of years I have been using Gsuite as an smtp relay for discourse. Today I found t…

I just fired up a Discourse install on GCE, with my credentials, and got the same error (having set up my relay to just rely on authentication). ======================================== ERROR ======================================== UNEXPECTED ERROR end of file …

Is there any chance this is a Gmail SMTP issue?

Seems like it. I don’t know how to troubleshoot it, and my attempts to fix it so far have gone nowhere. They likely changed something, Discourse can’t handle it, and there’s of course no support.

I’ve had good luck on these forums before helping track down and solve issues. Not sure why this one is so quiet.

It’s possible that it’s an gmail/gsuite smtp issue, but @Syonyk mentioned he was able to manually send an email through telnet on his droplet. I’m not nearly experienced enough to know how g-suite might interpret traffic dispatched from the site compared to manually sent message, but that seems to …

Without a good trace of the SMTP conversation from Discourse, I don’t know how to troubleshoot any further - and I don’t know how to get those traces.

Ein weiterer Bericht über Probleme: DigitalOcean → smtp-relay.gmail.com

Kann jemand leicht von einer nicht-DigitalOcean-VM testen? GCE oder etwas Ähnliches?
