Dead mail server on active company email

[vgonda]

Using this email_verifier to verify an email that uses a company domain name causes an out of mail server error. So when a user puts in [my-name]@[my-company].com, they get the "Email appears to point at a dead mail server" error message. This shouldn't happen since it is a real, actively used account.

Are you using the gem locally on your computer or from some publicly visible server? The SMTP server in most cases needs to be able to verify it can connect back. That may be the issue in this case.

I'm having the same problem one of my macbook pros. So yes I'm using it locally on my computer. Only, I don't see this behavior on my iMac at work. Also, the code works fine when pushed to heroku.
