This repo contains a list of disposable and temporary email address domains often used to register dummy users in order to spam/abuse some services. Also useful for filtering your email list to increase open rates (sending email to these domains likely will not be opened).
I originally collected them to filter allowed domains for new user registration at usegalaxy.org and later merged them with other lists I have found online. I cannot guarantee all of these can still be considered disposable but I did go through all of them at one point to check.
Feel free to create PR with more or request removing of your domain (with reasons).
Use
cat disposable_email_blacklist.conf your_file | sort | uniq > disposable_email_blacklist.conf
to add contents of another file in the same format (domains on new line without @).
