Hi daviesian,
While I moved on from this, FYI, I’m still seeing the same error which is wrong:
“You have enabled Custom SMTP for email sending - did you configure it correctly?”
also I’ll repeat that I think it makes sense to set a default “from_address” to be the same as in the custom SMTP server username.
Of course, ideally, I hope you resolve the issue with Anvil SMTP server as it has been causing me (and many others) lots of issues with emails never being delivered.
