Email Verification

E-Mail Verification and Domain Validation via API. Checks an email address against blacklist and availability of mailhost. Blacklisted domains and email addresses are simply stored in a text file. Easy to edit.

Functional API for E-Mail and Domain Verification.

• Email address verification against domain black- and whitelist (automated updates via online service trashmail-blacklist.org)
• Determination of availability of a mailhost. (MX and A Resource Record)
• Validation of Top Level Domains. (list of TLDs (punycode encoded) pulled from IANA stored in local textfile, automated monthly update)
• Syntax validation of domainnames
• Syntax validation of hostnames (punycode encoded)

Domains are listed in easy to edit text files blacklist.txt and whitelist.txt which are stored in the repository of this module.
