Hi there -
I have run through everything in the troubleshooting guide and still cannot get that registration email to send.
In Sparkpost mail, it shows that an email was blocked last night when I tried to register, but nothing today (I have tried twice to register). The reason it shows is:
550 5.7.1 Unconfigured Sending Domain \<[discourse.bite-nutrition.com](http://discourse.bite-nutrition.com)\>
I changed the custom commands at the end of app.yml to this:
## If you want to set the ‘From’ email address for your first registration, uncomment and change:
## After getting the first signup email, re-comment the line. It only needs to run once.
- exec: rails r “SiteSetting.notification\_email=‘noreply@bite-nutrition.com’”
When I look at the production log, I see this:
```
Sent mail to gina@bite-nutrition.com (509.7ms)

```
Sparkpost mail shows sending domain is “ready to send”.
DNS is configured
Haaaaalp! I’m soooo close!

This is concerning, are you out of memory? Discourse will not function correctly if redis is not running.

How would I check that?

running `free -h` on the host is a good start, there should be quite a few topics on meta regarding memory.

Hey All
Sorry to necro this thread, but I am also getting the same error 6379 in my log, I destroyed my droplet and started over like @Gina_Patterson but I’m still getting the same message. My free -h check reads

I have gone through the email registration trouble shooting guide - no avail..
Curiously my sparkpost records show my emails having 100% rejection because:
“550 5.7.1 Unconfigured Sending Domain”
I HAVE verified the domain via DKIM and abuse@/postmaster@… however I’m not sure what I still need to configure. I’m using alternate SMTP port 2525 in the app.yml because I heard google blocks 587. (I’m trying to send my registration email to a paid g suite account).
Any help would be greatly appreciated. I did try to exhaust all other options before asking for help here thanks.
-Andrew

I destroyed my droplet and rebuilt it using mailgun for a smtp server, works fine now! Cheers all.
