List of email address domains that are known to be from spam / disposable hosts

List of disposable email domains

, _(*1)

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., _(*2)

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., _(*3)

Whitelist

The file whitelist.conf gathers email domains that are often identified as disposable but in fact are not., _(*4)

Example Usage

Python, _(*5)

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 thanks to @di, _(*6)

>>> from disposable_email_domains import blacklist
>>> 'bearsarefuzzy.com' in blacklist
True

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);
}

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

Contributing

Feel free to create PR with additions or request removal of some domain (with reasons)., _(*10)

Use, _(*11)

$ cat disposable_email_blacklist.conf your_file | tr '[:upper:]' '[:lower:]' | sort -f | uniq -i > new_file.conf, _(*12)

$ comm -23 new_file.conf whitelist.conf > disposable_email_blacklist.conf, _(*13)

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., _(*14)

Changelog

• 12/6/16 - Available as PyPI module thanks to @di, _(*15)

• 7/27/16 - Converted all domains to the second level. This means that starting from this commit 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, _(*16)
