SMTP failing for some domains

▶ Reproduction steps
  1. Configure a "From email address" in SMTP that ends in .engineering
  2. Use the SMTP mailer tool to test
😢 Unexpected result
Incident occurs. If I swap to a .dev email I have then everything works. The only thing I noticed is that the client identifies as 250-ec8f088d579e.localhost and seems to be talking to my Chevereto instance (photos.test.engineering). That's kind of odd.

That's raw SMTP server output, Chevereto is just reporting what the SMTP server replied. Perhaps you need to check your dns email records.
