Bulk Email Validator

Question

Hello all,

I wish to either make use of a freely available email validator (software, script or online service). If this does not exist, are there some free PHP classes that I can make use of to validate email addresses?

I have about 100 emails and before I send to these emails I would like to check their validity. I don't want my server to be blacklisted because of bounce backs.

Please note, I am not looking for just a a syntax checker. I am talking about DNS and SMTP validation.

The ideal solution would be a pHP script or the like that I can setup locally or on my server.

Thanks all for any help

try running gethostbyname() on whatever is after the @ and if it doesnt return an IP, its not a valid DNS
