email-validator: Perform basic syntax and deliverability checks on email addresses.

[ agpl, program, utils ] [ Propose Tags ]

Validate an email address using three techniques:

  • Ensuring that the length of local and domain parts is within the RFC-specified limits.

  • A syntax check using a regular expression, or the full RFC 5322 grammar (see the --rfc5322 option).

  • Confirmation of the existence of an MX record for the domain part of the address. This is not required; in fact many domains accept mail via an A record for e.g. example.com which is used in lieu of an MX record. This behavior can be controlled via the --accept-a flag.

These checks are performed in parallel using the number of available threads. To increase the number of threads, you can pass the appropriate flag to the GHC runtime.

This will set the number of threads to 25:

$ email-validator +RTS -N25 < addresses.csv

Input

The input (via stdin) should be a list of email addresses, one per line. Empty lines will be ignored.

Output

Valid email addresses will be written to stdout, one per line.
