Well, that’s a pretty good tool…
I initially tried and the email never arrived.
I received a notification from MailJet that I was trying to send an email from noreply@www.zzz.net, which is one change I tried a bit earlier following the Troubleshoot procedure.
I removed the www, essentially going back to my previous config, but this time it worked… I think I’ll never know why.
Thank you for you help, everything was going so well until Amazon SES denied me and had to find an alternative.
Here is the config that works now:
DISCOURSE_SMTP_ADDRESS: in-v3.mailjet.com
DISCOURSE_SMTP_PORT: 587
DISCOURSE_SMTP_USER_NAME: xxx
DISCOURSE_SMTP_PASSWORD: "yyy"
DISCOURSE_SMTP_ENABLE_START_TLS: false # (optional, default true)
DISCOURSE_SMTP_DOMAIN: mydomain.net
DISCOURSE_NOTIFICATION_EMAIL: noreply@mydomain.net
