The forums I maintain at [users.rust-lang.org](http://users.rust-lang.org) and [internals.rust-lang.org](http://internals.rust-lang.org) are set up to use the [users@rust-lang.org](mailto:users@rust-lang.org) and [internals@rust-lang.org](mailto:internals@rust-lang.org) emails respectively for reply-by-email and ‘email in’ is checked. When I send an email to either of those addresses though I get the following response: ```plaintext We're sorry, but your email message to ["users@rust-lang.org"] (titled new topic test) didn't work. None of the destination addresses are recognized. Please make sure that the site address is in the To: line (not Cc: or Bcc:), and that you are sending to the correct email address provided by staff. ``` What am I missing? ---

Can you take a screenshot of the category settings? ---

Yes, below. From your hint I tried to update ‘custom incoming email’ address for ‘uncategorized’ to ‘users@rust-lang.org’, but after clicking ‘save’ the setting did not seem to take. ![](https://global.discourse-cdn.com/meta/original/3X/e/0/e08946b2b20293c18b57c98f7009a77334bb07ec.png) ![](https://global.discourse-cdn.com/meta/original/3X/a/b/abf92c323bfb37c1b7f7b19496111fc7dbd4d1c7.png) ---

Hm… try editing something other than uncategorized? Might be locked for uncat. ---

I got it working! The behavior I encountered in doing so was unexpected though. Here are the steps I did: - In ‘uncategorized’ settings I entered ‘users@rust-lang.org’ for ‘custom incoming email address’ - Click ‘save changes’ - Changes appear to save successfully. - Go _back_ into the settings for ‘uncategorized’ and the ‘custom incoming email address’ is empty. That is where I got confused. - Went to another category and entered the same email address, click save, got an error message. So that clued me in that maybe the original attempt did work. Sending emails does create uncategorized topics now. Thanks for your help @riking ---

Wow, this bug was affecting all the fields in the `Settings` tab for “uncategorized” category. The fields were not showing as updated when opening in edit mode. Sent a fix 🐛 [https://github.com/discourse/discourse/pull/3161](https://github.com/discourse/discourse/pull/3161) Thanks for bringing this in our notice @brson! ---
