## MOD Title: Live Email Validate (LEV)
## MOD Author: Wulf_9 < webmaster@zodiac-infosystems.co.uk > (Wulf) http://www.zodiac-infosystems.co.uk
## MOD Description: When a user signs up or edits their email address, this MOD will
##                  attempt to verify it via the DNS MX records and a test SMTP session,
##                  returning true or false as appropriate.
##
## MOD Version: 1.0.1
##
## Installation Level: Easy
## Installation Time: 10 Minutes

## For security purposes, please check: http://www.phpbb.com/mods/
## for the latest version of this MOD. Although MODs are checked
## before being allowed in the MODs Database there is no guarantee

##############################################################
## Author Notes:
##
## This does a live test of a user's mailbox, using the MX
## record for the supplied domain (the part after the @).
## If there is a network issue or all the hosts are down or
## don't respond, it will return 'false', meaning that
## the supplied email address won't be able to be checked
## until the connection works. If this will be a problem,
## this MOD can be enabled/disabled via the ACP. The default
## setting is 'off' after installation. As usual, you are
## advised to check your board config after installing any
## MODs which alter your settings or database.
##
## If not installing via EasyMOD or you won't/can't do the SQL,
## you MUST run the setup script from your forum root before
## attempting to enable the LEV feature via the ACP.
##
## If you use EM to do the install, it will run the SQL for you so
## delete the update script from your forum root without running it.
##
## The Q/A entries in the FAQ page will only be displayed
## if LEV is enabled, allowing for contextual feedback.
##
## Works on unix and windows boxes, since it will auto-detect
## the OS platform and call the relevant function.
##
## Thanks to Alejandro Gervasio at devshed.com for some handy php tips.
##
## ACP option coded by The Defpom http://www.radiomods.co.nz/forum/ have a look for my other forum MODS.
##
## Update for non-RFC-compliant mailservers with thanks to Markus Petrux ( http://www.phpmix.com )
