mailchannels 500 error even though DomainLockdown, DKIM, SPF, worker example script, and everything

It just doesn't work!

500 usually means server error, what's the response body?

Not a direct solution to your issue, but I would recommend avoiding MailChannels and using some other service like Amazon SES, Sendgrid, Postmark, etc.

There are a lot of security implications and their responses to the situation have been very undesirable. Further reading:

Ah good to see im not alone. Also experiencing this issue here. And looking for alternatives. I assume there is no SMTP package out there which would be usable on worker side?

Not to my knowledge. I would recommend SendGrid personally - I’ve had good experiences with them

i went for sendgrid and it works already quite well for me
