 List of disposable email domains
 ========================
 
+![Licensed under CC0](https://licensebuttons.net/p/zero/1.0/88x31.png)

 This repo contains a [list of disposable and temporary email address domains](disposable_email_blacklist.conf) often used to register dummy users in order to spam/abuse some services. 
 
 Originally collected to filter new user registration at https://usegalaxy.org and later merged with other lists found online. I cannot guarantee all of these can still be considered disposable but they probably were at one point in time.
