I tried to add a bunch of emojis, and none of them worked. When I try to click any of them, it says "Undefined" in the post. Since none of my added emojis have ever worked, I would like to delete them all and try adding them with new shortcodes. How do I do this, and what should be the format of a shortcode(as what I was trying obviously was not accepted)?

Hi. I got a new instance of Lemmy up on my server, but outgoing emails aren't working with Gmail. I have a paid account with Gmail, and previously have used outgoing mail with other services(like phpbb and Mastodon), and they worked. If you can provide some help, that would be much appreciated. Thanks!
