forum is failing to send email
I just logged into the forum now and was told by the UI there was an "advice" from the site. Looking at the admin dashboard, it says:
There are 195843 email jobs that failed. Check your app.yml and ensure that the mail server settings are correct. See the failed jobs in Sidekiq.
The "failed jobs" link leads to a lot of failures that look like:
Jobs::HandledExceptionWrapper: Wrapped Net::SMTPServerBusy: 454 4.7.1 <REDACTED@proton.me>: Relay access denied
I think that the mail server is misconfigured and doesn't accept outgoing mail for anything but torproject.org.
