I’ve been self-hosting Discourse for many years, and had several instances happily configured and running on a fairly beefy machine. Today I noticed that one of my forums had gone down. The initial culprit looked to be lack of disk space, which I fixed. I then restarted the Discourse instance. How…

Is there a way to “downgrade” discourse to an older working version (say 2.8.0 stable or 2.9.0 beta3) until this is worked out?

I decided to spend one more half hour to dig into this and I think I found the cause. This seems to be related to the move to Rails 7, which updated net-smtp from 0.1.0 to 0.3.1, which changed the defaults. The way the smtp gem calls net-smtp does not disable enable_starttls_auto and openssl_verif…

Nice work, Richard! That would have taken me two hours if not twice that. For me it’s easier to succumb to dealing with the new defaults. [图片] Richard - Communiteq: The way the smtp gem calls net-smtp does not disable enable_starttls_auto and openssl_verify_mode , it only enables it when enable…

Nice job @RGJ ! While we anticipate a fix, on a side note, it would be good if this problem didn’t cause the cascade of issues that I experienced, which nearly brought by forum down completely. Specifically: The email failures seem to be retried extremely quickly, which causes the sidekiq queue to…

In my case when I encountered the failure after the upgrade it was using TLS with a third party server and the name on the certificate matched the smtp server name. I just had one failure however. I haven’t rebooted or upgraded since to avoid further issues. I’ll try an update once the patch has bee…

+1 :worried:really frustrating bug

Can’t the gem be rolled back? I would be surprised if it didn’t get attention since this is a “core” functionality, the ability to send emails and for some it’s also causing an outage due to temporary files and cpu overrunning the server. The core stability of the forum is being disrupted here.

Please don’t forget that this can easily be resolved by configuring your mail server properly as well.

AFAIK my server is configured properly. Certificate name matches smtp host name, STARTTLS on port 587. I’m wondering why I faced the issue? Thanks for opening a new ticket. Given your understanding, could you shed some light on the combinations of the two variables you pointed out in the YML file -…

我会先在 Contribute > Bug 板块创建一个主题，但由于这本质上是一个上游 gem 的问题，我不确定它会获得多少优先级。
