❓ Question

I selfhost my own NTFY server. To not let everyone use my server I have the following settings in server.yml, so only authenticated users can post on topics.

 auth-file: "/etc/ntfy/user.db"
 auth-default-access: "deny-all"

Yesterday I setup the incoming email settings:

smtp-server-listen: ":25"
smtp-server-domain: "domain.tld"
smtp-server-addr-prefix: "ntfy-"

At the beginning it would not work and I would get a `Message not delivered response'

The response from the remote server was:

554 5.0.0 Error: transaction failed, blame it on the weather: error: {"code":40301,"http":403,"error":"forbidden","link":"https://ntfy.sh/docs/publish/#authentication"}

Till I made the topic accessible to everyone then it worked perfectly. Now my question is if there is a way to post incoming email to a user locked topic? A way to pass on credentials or a setting I missed.

Thanks for the awesome work, NTFY has fully replaced pushover for me and use it for all my services.

As seen in the last code example of this section of the docs, you can include an access token in the "to" email address.

So instead of sending to ntfy-topic@domain.tld you'd send to ntfy-topic+tk_abc123...@domain.tld

Thanks, awesome. I had not found that option in the documentation. Thanks again
