Most probably CPANTS databases are being regenerated from scratch due to major changes in Kwalitee metrics or updates of relevant modules/perl. Usually this maintenance takes about a day or two, and some of the information may be old or missing tentatively. Sorry for the inconvenience.
Add a META.yml to the distribution. Your buildtool should be able to autogenerate it.
Change the permissions of Build.PL/Makefile.PL to not-executable.
Add 'use strict' (or its equivalents) to all modules, or convince us that your favorite module is well-known enough and people can easily see the modules are strictly written.
Error: Mail::IMAPClient, Mail::IMAPClient::BodyStructure
Add a META.json to the distribution. Your buildtool should be able to autogenerate it.
Use the prompt() method from ExtUtils::MakeMaker/Module::Build.
Define the license if you are using in Build.PL. If you are using MakeMaker (Makefile.PL) you should upgrade to ExtUtils::MakeMaker version 6.31.
Add 'use warnings' (or its equivalents) to all modules, or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.
Error: Mail::IMAPClient, Mail::IMAPClient::BodyStructure
Split the distribution, or fix the version numbers to make them consistent (use the highest version number to avoid version downgrade).
Error: 0.000002,2.002001
This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
List all modules used in the Makefile.PL/Build.PL in META.yml configure_requires
