Caddy registration confirmation seen as spam

[details=“Summary”]
Hiya

Many thanks for Caddy Server, it’s a very helpful new addition to the landscape!

I noticed that on signup, the registration email was considered spam by ProtonMail (uses SpamAssassin) because sendgrid was found in spamcop etc…

Also @caddy.community is different from the sending domain @email.caddyserver.com

Just mentioned it, in case of help.

Headers cannot be attached as trip 4 link limit for new users, happy to share another way.

Thanks for letting us know. Can you attach the headers as a code block? They shouldn’t turn into links then.

Here they are, I used admin@protonmail.com in place of my email address.
