My Public IP vs SMTP Lookup使用状況と統計

The SMTP Lookup utility is for anybody who is struggling to send e-mails because they are not sure of the correct server details for their e-mail account. Using an advanced server lookup process the SMTP utility will attempt to find the correct SMTP server to use for any valid domain or e-mail address that you enter (including support for Internet Service Providers and stand alone e-mail providers such as Yahoo, Gmail etc). For network administrators and advanced users the utility will also provide complete MX record details for mail delivery debugging. It's a developer tool that we've been using in-house for over 8 years now available for the first time on iOS devices.
