List of disposable email domains ======================== [![Licensed under CC0](https://licensebuttons.net/p/zero/1.0/88x31.png)](https://creativecommons.org/publicdomain/zero/1.0/) 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. Whitelist ========= The file [whitelist.conf](whitelist.conf) gathers email domains that are often identified as disposable but in fact are not. Example Usage ============= **Python** ```Python blacklist = ('disposable_email_blacklist.conf') blacklist_content = [line.rstrip() for line in blacklist.readlines()] if email.split('@')[1] in blacklist_content: message = "Please enter your permanent email address." return (False, message) else: return True ``` Available as [PyPI module](https://pypi.python.org/pypi/disposable-email-domains) thanks to @di ``` >>> from disposable_email_domains import blacklist >>> 'bearsarefuzzy.com' in blacklist True ``` **PHP** contributed by @txt3rob and @deguif ```php function is_temp_mail($mail) { $mail_domains_ko = file('disposable_email_blacklist.conf', FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES); //Need to ensure the mail contains an @ to avoid undefined offset return in_array(explode('@', $mail)[1], $mail_domains_ko); } ``` **Ruby on Rails** contributed by @MitsunChieh In resource model, usually it is `user.rb` ```Ruby before_validation :reject_email_blacklist def reject_email_blacklist blacklist = File.read('config/disposable_email_blacklist.conf').split("\n") if blacklist.include?(email.split('@')[1])    errors[:email] << 'invalid email' return false else return true end end ``` Contributing ============ Feel free to create PR with additions or request removal of some domain (with reasons). Use `$ cat disposable_email_blacklist.conf your_file | tr '[:upper:]' '[:lower:]' | sort -f | uniq -i > new_file.conf` `$ comm -23 new_file.conf whitelist.conf > disposable_email_blacklist.conf` to add contents of another file in the same format (only second level domains on new line without @). It also converts uppercase to lowercase, sorts, removes duplicates and removes whitelisted domains. Changelog ============ * 12/6/16 - Available as [PyPI module](https://pypi.python.org/pypi/disposable-email-domains) thanks to @di * 7/27/16 - Converted all domains to the second level. This means that starting from [this commit](https://github.com/martenson/disposable-email-domains/commit/61ae67aacdab0b19098de2e13069d7c35b74017a) the implementers should take care of matching the second level domain names properly i.e. `@xxx.yyy.zzz` should match `yyy.zzz` in blacklist more info in [#46](https://github.com/martenson/disposable-email-domains/issues/46)
