I recently came across a tool which will take a list of email addresses, and attempt to cleanse it of the nonsense addresses that people use when wanting to download/sign up for something without receiving the resulting emails (e.g. firstname.lastname@example.org).
The tool in question was Email Validation Tool by Softsea.
It first rules out spurious email domains by performing a DNS lookup, and then can also go on to connect to the appropriate SMTP server to ask it whether the mailbox in question actually exists. Unfortunately I was not able to configure the tool correctly in order to get this second step to work, as I could not understand what configuration data it needed (it asked for an SMTPID?).
My question is this:
Can anybody recommend/share their experience of a slightly more user friendly tool to achieve this? or failing that point out where I'm going wrong with this one in particular!?
The tool wouldn't need to be free, but I'm looking for one that is pretty straight forward to use.
