Provides API for E-Mail and Domain Verification. Options:

  • Check email address against blacklist (editable textfile) If a domain service https://trashmail-blacklist.org/ updated weekly) Use the implementation on your own risk. You maybe need a special license to call fiddlemail.com, mogelmail.de or any other domain related to this service.
  • Check availability of mailhost. (MX and A Resource Record)
  • Validate Top Level Domain. (list of TLDs (punycode) pulled from IANA stored in local textfile, updated monthly)
  • Validate Domainname (Syntax)
  • Validate Hostname (Syntax)

Blacklisted domains are listed in an easy to edit text file blacklist.txt which is stored in the repository of this module.
