'Address Validation' Tab

..:: Objectives

  • Define valid domain extensions.
  • Define valid top level generic domains.
  • Define domain extensions to reject.
  • Define keywords to reject.
  • Select a file containing black listed email addresses.

Here is a screenshot of the 'Address Validation' tab :

When the software has to calculate if an email address is invalid in the 'Manage Lists' and 'Merge Multiple Lists' tabs, the following algorithm is used :

1) all email addresses are checked syntactically according to RFC 2822.
2) all email addresses are checked against the parameters defined inside the 'Address Validation' Tab.

Let's explain those parameters :

  • 'Valid Domain extensions' : Top level domains country codes

    If an email address is not ended by any of these values (and not by any of the top level generic domains, see next paragraph) , then it is flagged as invalid.

    For example, "someone@yahoo.uk" is valid but not "someone@yahoo.zz" as "zz" is not a known country code as opposed to "uk", "us", "fr" ...
     
  • 'Valid Domain extensions' : Top level generic domains

    If an email address is not ended by any of these values (and not by any of the top level domains country code, see previous paragraph), then it is flagged as invalid.

    For example, "someone@yahoo.com" is valid but not "someone@yahoo.temp" as temp is not a known top level domain as opposed to "com", "net", "org" ...
     
  • 'Domain extensions to reject' : User defined extensions

    If an email address is ended by any of these values, then it is flagged as invalid.

    Useful if you want to reject email address from some countries. For example, if you want to get rid of email address from China, just add 'cn' to the list.
     
  • 'Keywords to reject' : User defined keywords

    If an email address contains any of these keywords (user and or domain), then it is flagged as invalid.
     
  • 'Black Listed Email Addresses' : Black List file

    If an email address from this file is found in the list being scanned, then it is flagged as invalid.

    Note that you can edit all these parameter values by clicking on their respective 'Edit' buttons.
