I'm configuring emails for my discourse hosting. Discourse is hosted at discuss.xxxx.com.
I read in the documentation that for emails to work properly, we must verify and use the subdomain, e.g. discourse.example.com. So in my case sending domain must be discuss.xxxx.com
I'm using SendGrid to send emails and in SendGrid white label domains can not have the same name as one of the subdomains in DNS. So I'll not be able to have discuss.xxxx.com as my verified sending domain.
I'm curious, can I set sending domain different than the discourse domain? I would prefer to set sending domain as firstname.lastname@example.org or forum.xxxx.com ..what can be implications of this?
Looking forward to hear your views on this
