SMTP Lookup
Read full descriptionHide full description
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.

AC20 and SMTP Lookup are too close to call on the numbers: across 5 compared parameters ā price, ads, in-app purchases and device support among them ā neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
