Problem
I am using command like `sendmail -bv example@othesite.com` to verify some email address to confirm the address is valid or not before sending actual email to people. it works for most sites I tested. But sometimes, I am using the sendmail for some website that will give me all pass no matter what the address name I put for the same site. For example: `sendmail -bv yyyyyy@othersite.com` where `yyyyyy` can be anything that also passes the command and always reported out "`yyyyyy@othersite.com` verified". It seems correct but I think that should be something wrong behind. Why ? Other command checking mail address on linux will be reliable and available, how and what command does this?
