  • verify email list - created for user's who what instant verification through our web interface (up to 30 emails per click)

Yahoo verification notices

All valid emails will be marked as "ok", all emails that not exist will be marked as "fail".
Some valid email addresses are disabled so during mail send you can get some bounces like this:
: host[] said: 554
delivery error: dd Sorry your message to cannot be
delivered. This account has been disabled or discontinued [#102]. - (in reply to end of DATA command)
The research during long time do not give any solution for detect disabled emails without mail send.
We check some other popular software and services and find that so of it do not verify yahoo at all or having the same problem.
