Anonymous Monk has asked for the
wisdom of the Perl Monks concerning the following question:
I recently developed a script for someone that I host on my server, they run a site which allows users to enter their email address to signup for a contest, At the moment I only have a very simple regex to validate the syntax of the email - this contest site gets about 1,000 signups a day, of which of the emails the server sends out, I'm getting about 50 bounce and just sit on the server waiting for a retry, mainly this appears to be due to users spelling their email address wrong..
Then I stumbled upon Email::Valid yesterday which appears to also do an mx check on a domain, my concern with so many emails to check that this will cause a very high load on the server..
Anyone have any opinions?
