问题
I just used the email_verifier gem (https://github.com/kamilc/email_verifier) to check if a list of emails was valid (ie. email account exists on a given server). Unfortunately this has blacklisted my own IP on several servers since it turns out that this gem pretends to send email.
Is there a (different) way to verify that an email account exists without getting blacklisted?
