When I enter the plugin link it tells me: This is not a valid plugin / mod.
Please explain why I can't add the following plugin: https://www.spigotmc.org/resources/postalservice.10434/
but the external site is dev.bukkit.org
What
The official sites are dev.bukkit.org and spigotmc.org
And yes the link that you sent is from spigotmc.org, but the download button says "download via external site" so it can't be added
the button on spigotmc.org redirect to https://dev.bukkit.org/projects/postalservice
