This host checks whether a business email address exists before any email is written to it, so that mail is not sent to addresses that would bounce. It asks the receiving mail server at the recipient stage of an SMTP conversation and disconnects before any message is sent. It never sends email.
Connections come from probe.leadclawcheck.com, at a low rate per mail server.
To have your domain excluded, or to report a problem, write to abuse@leadclawcheck.com. We exclude domains on request, usually within a day. We keep only a one-way hash of each address checked, with its answer, for at most 30 days.
