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. It is also useful for filtering your email list to increase open rates (sending email to these domains likely will not be opened).

I originally collected some of 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 they probably were at one point in time.

Feel free to create PR with additions or request removal of some domain (with reasons).

Use

cat disposable_email_blacklist.conf your_file | sort -f | uniq -i > new_file

to add contents of another file in the same format (domains on new line without @).
