Hi team,
I just noticed that when installing the latest version of the SDK (v6.0.1 at this point in time) I get this warning when running composer install:
Class Postmark\Models\Stats\PostmarkOutboundEmailClientStats located in ./vendor/wildbit/postmark-php/src/Postmark/Models/Stats/PostmarkOutboundClientStats.php does not comply with psr-0 autoloading standard. Skipping.
Composer doesn't fail, but guessing that class might not work if someone needed it? (I don't use it, so doesn't impact me)
(Tested with composer versions: 2.5.4 and 2.6.6)
Thanks!
