I’ve looked at the configs and I can’t figure out how to change the host that email is being sent from, other than changing the
DISCOURSE_HOSTNAME variable. However, based on the comments, If I change that to say… example(dot)com, then if I visit VPS.provider.example(dot)com, I will no longer see the discourse service.
Alrighty, let’s see if I can make that a bit clearer now… (my real domain is replaced with example.com)
- My VPS hosting discourse is on a different machine than my email server (due to the fact that I don’t trust the discourse-setup and launcher scripts being run as root).
- My email server serves email from example(dot)com
- Discourse is running on myvps.do.example(dot)com
- Discourse is logging into smtp.example(dot)com to send emails
- Discourse is sending emails from firstname.lastname@example.org(dot)com
- Google receives the email and throws it away due to strict SPF and DKIM rules
- Google sends me an email of said rejection by the next day via the DMARC system
I’m not sure what I can do to fix this, is there anyway to change the sending address? (I’ll be taking a look into spoofing the header.from=myvps.do.example.com from the postfix side to see if that helps at all) I’m able to login to the system since I can send emails to example(dot)com and be just fine, but sending to other email providers is another story.
