🐞 Describe the bug
I'm attempting to use ntfy to receive email alerts from outside my private network. I've setup an aname and mx record, however upon sending an email using gmail, I get a bounce back(personal information censored):

Message not delivered
There was a problem delivering your message to test_alerts+mytokengoeshere@notify.mydomain.com. See the technical details below, or try resending in a few minutes.

The response from the remote server was:
554 5.0.0 Error: transaction failed, blame it on the weather: error: {"code":40101,"http":401,"error":"unauthorized","link":"https://ntfy.sh/docs/publish/#authentication"}

If I send a test email using nc, it works fine.

This has something to do with the token authentication when coming from the internet. I changed the topic access to write only and now it works.

You can try to manually modify your token in the sqlite database to be all lowercase and try if that works.

sqlite3 /var/lib/ntfy/user.db
select * from user_token;
update user_token set token='...' where token='...';

I'm going to assume this is a dup of https://github.com/binwiederhier/ntfy/issues/773, let me know if you think it is not.
