you have to use a proper from_address and helo_host.

you have to use a proper `from_address` and `helo_host`.

Hi,
I am facing this same issue. I am trying to test validity of an Yahoo email. Many online tools say, the email is False or the 'mailbox not found error'.
But, the library says 'True'.
Could you please explain if I am missing something?

Also, what are the values to pass for from_address and helo_host?
I tried passing from_address='my_gmail_address' and helo_host='gmail.com' , but still it returned True.

If you get True, that means yahoo's servers in the SMTP conversation said they would accept the email coming from that address, going to the address you passed in the "to" parameter. Not much I can do there, yahoo does this probably to provide false positives for spammers testing for emails to spam. Or you might have hit an MX that will try to relay every email to yahoo's servers.

Look into the SMTP protocol to understand what the HELO command does, but basically you should use your IP's fully qualified domain name.

On a second thought, there's something off. I'll look into this later.
