Hello, I’m almost a complete noob at this.
I followd Discrouse’s install instructions and created an account on SendGrid to serve as a mail server for Discourse. However, I seem to cannot validate the domain (whitelabeling) that I added on the SendGrid account. It seems that I don’t know how to add the CNAME records for my droplet’s domain, because I’m getting the following message:
Error validating domain: Expected CNAME for “mail.medaddon.com” to match “u2210027.wl.sendgrid.net”. Expected CNAME for “s1._domainkey.medaddon.com” to match “s1.domainkey.u2210027.wl.sendgrid.net”. Expected CNAME for “s2._domainkey.medaddon.com” to match “s2.domainkey.u2210027.wl.sendgrid.net”.
I hope it’s still propagating.
Can somebody help, please? :D

Hi!
In your do admin panel go to Network > Domains > yourdomain.com
Then, create the following cnames:
| Source | Target |
|---|---|
| u2210027.wl.sendgrid.net. | |
| s1.domainkey | s1.domainkey.u2210027.wl.sendgrid.net. |
| s2.domainkey | s2.domainkey.u2210027.wl.sendgrid.net |
Notice two things:
- In the source don’t put the whole domain aka mail.yourdomain.com; just the subdomain aka mail
- In the target append a dot

SendGrid shows you something like
s1.domainkey.yourdomain.com s1.domainkey.u1XXXXXX.wXXXX.sendgrid.net
in DigitalOcean when adding a CNAME… drop the yourdomain.com from the first value
so enter
s1.domainkey -> s1.domainkey.u…
when you see the setup after saving… you will see something like
s2._domainkey.yourdomain.com. 1800 IN CNAME s2.domainkey.u1XXXXXX.wXXXX.sendgrid.net.
or something… then validation should happen fairly quick
