Email login: how can I set the "from" address name to be different from the "sign in with xyz" name?

[tremby]

As far as I can tell, the same configuration for email login providers (I'm using Mailgun) is used for both the name on the "from" email address and the name on the "log in with xyz" button.

export const { handlers, signIn, signOut, auth } = NextAuth({
	adapter: PrismaAdapter(prisma),
	providers: [
		Google,
		Mailgun({
			from: "auth@example.com",
			name: "my app",
		}),
	],
});

I've tried setting from to things like My App <auth@example.com> and this throws an error.

So as far as I can tell there's only name, and whatever I set that to appears both in the "Sign in with {name}" button and in the "from" email address which is included with the email ("{name} auth@example.com").

• "Sign in with email" makes sense, but a sign in email coming from someone called "email" does not.
• An email from "auth" or from "My App" makes sense, but "Sign in with auth" or "Sign in with My App" does not.
• The default seems to be "Mailgun", which doesn't make sense to an average user in either case.

I know that I can override the sendVerificationRequest method as detailed here but I'm otherwise happy with that method and it seems mad to duplicate the whole thing just to change the "from" address.

I feel like I must be missing something.
